This is why one of the subject experts of AllAssignmentHelp.com has created this blog post where you get to know all about magnetism.
Let’s start the discussion from the basics and learn about the Magnetism topic in detail.
Understand the Basics Of Magnetism
What Is Magnetism?
Magnetism which is commonly dealing with the field of physics comprises a lot of formulae and studies of the forces of the magnetic field on particles. In general, magnetism is a phenomenon involving magnetic fields that develop from the movement of electric charges.
There are several different variations of this movement:
- May take the form of a charged particle traveling through space
- An electric current flowing via a conductor
- Or the motion of an electron within an atomic orbital
In addition to electricity flowing via a wire, basic particles like electrons’ spin magnetic moments also contribute to the creation of magnetism. As a result of the magnetic field created by electrons orbiting atomic nuclei, every matter is magnetic to some extent.
What Are Magnetic Fields?
The magnetic field is a vector field that specifies the magnetic force on moving electric charges, currents or magnetized materials. The direction of a magnetic field at a given point is defined as the direction of the force that would be exerted on a moving positive charge if it were to move in that direction.
Electromagnetism
Electromagnetism is a phenomenon that deals with the interchange of electricity with magnetism. An electric current comprises moving electric charges and whenever there is a flow of electric current in a wire, it produces a magnetic field around the wire. This principle forms the core of many technological devices like electric motors and transformers.
Magnetic Materials
Materials can be classified based on their magnetic properties into three categories: Diamagnetism, Paramagnetism and Ferromagnetism, there could be other types of magnetism but these are the most common types of magnetism. Diamagnetic materials include all elements that do not align their magnetic fields and are weakly attracted in a magnetic field while ferromagnetic materials include all elements that have strong magnetic properties including iron, cobalt, and nickel and are used to make permanent magnets.
Types of Magnets
Permanent and temporary magnets are two different types of magnets.
Even when there is no external magnetic field present, permanent magnets are still magnetic. Temporary magnets, like an iron pin, lose their magnetic properties when they are withdrawn from the magnetic field of the environment.
Students who are studying magnetism should have a clear understanding of physics. However, if they fail to understand physics, they can take physics assignment help online as well. Other than this, they can always go for assignment help with magnetism topics as well.

The Nature of Magnetism
Natural magnets can be found as magnetic ore, of which the two primary forms are lodestone, also known as “leading stone,” and magnetite, commonly known as “iron oxide” (FE3O4). These two magnets will align themselves with the Earth’s magnetic field, which is always oriented north if they are hanging from a piece of string.
The needle of a compass is a practical example of this phenomenon. These naturally occurring magnets may be ignored for the majority of practical uses since they have relatively low magnetism and because artificial magnets developed by humans now come in a wide variety of forms, dimensions, and magnetic strengths.
Furthermore, the molecular structure of magnetic materials in the non-magnetic state is made up of dispersed magnetic chains or tiny, individually organized magnets. Since each molecule magnet is arranged haphazardly, it tends to cancel out its neighbour, resulting in zero or very weak magnetism.
A few Facts About Magnetism
Although the concepts of magnetism and electricity are distinct, they are not yet related. The generation of the electric current is supported by magnetism. We’ll provide you with a brief overview of the same here. Let us briefly discuss the same with you now. This will be beneficial for your online assignment about electricity and magnetism. You’ll know how magnetism and electricity are related to one another.
- The magnetic fields also produce the phenomenon known as magnetism. Yet another time, it has a physical aspect. All that remains of the magnetic field is the vector that affects the magnetic energy of the electric charge.
- The electric current that is a component of the spin magnetic moments and elementary particles are the sources of magnetism. Furthermore, there is more than only magnetism. Superparamagnetism, diamagnetism, ferromagnetism, antiferromagnetism, paramagnetism, and more are examples of electromagnetic fields.
- There are various uses for magnetism. The fundamental element that generates electric current is the magnetic field. The strength of the magnetic fields grows when they are close together, and the opposite occurs when they are not.
- Electromagnetism is a basic concept that is derived from magnetism. The method of creating magnetic fields using current and conductors is known as electromagnetism. Since all coalitions rely on electricity to function, the principles of electromagnetism are important. High-speed trains also make use of the electromagnetic idea.
What Are The Important Topics In Magnetism?
Interestingly, all the materials experience magnetism. Some of them experience stronger than others. However, to learn all this process and compile them in assignments, students get anxious. Thus they require an online assignment writing service with magnetism.
The fundamental yet important topics of magnetism are listed below which a student has to undergo while writing assignments.
Charge
Similar to mass, the charge is an essential feature of magnetism. Charge describes the interaction of matter and electric fields. While charge will lead the way into all of the concepts in electromagnetic, the mass will lead the charge into all of the concepts in mechanics, including forces, energy, and momentum.
Charge often referred to as q, is expressed in coulombs (C).
Electric Fields
Through its electromagnetic current, every charged particle communicates with other charged particles. Charges produce an invisible force field called an electric field, similar to how the planet produces a gravitational field.
It is denoted by ‘E’.
Formula: Electric Field = F/q. Unit of E is NC-1 or VM-1.
Magnetic Forces
The attractive or repulsive force that exists between the poles of a magnet and electrically charged moving particles is known as a magnetic force. Also, the Lorentz force law describes the magnetic force. In a magnetic field B, a charge q travelling at speed v experiences the Lorentz force, which is defined as follows:
qvBsin = Fb
Magnetic Fields
Any moving charge creates a magnetic field. Since electron beams and large-scale currents are all magnetic to some extent. It follows that even electron orbitals, which are the tiniest form of moving charge, can produce powerful magnetic fields. There is a polarity to magnetic fields known as north and south. Every magnet has a north end and a south end (called poles).
The magnetic field is donated as B.
The formula of the magnetic field is F=ILBsin.
Electric Potential
Electric potential is the potential energy that a hypothetical +1 C charge would have if placed in an existing electric field. It is often referred to as voltage or electric potential difference. The real potential energy that the charge you’re concerned with possesses is known as electric potential energy. Concerning a charge q in a field E with a connected potential V, this means:
Ue = qV
The term electrical potential is denoted by the Greek symbol Φ.
These topics are really complex to comprehend while writing assignments. However, you can pay someone to do assignment online to get well-written and explained solutions with a professional touch written by experts. Moreover, there are a lot of topics for which students can get physics assignment help in magnetism from these professional faculties.

Properties of Magnetism
We already know that magnetic materials make up magnets. The following properties are present in magnets:
- North and South poles are present in every magnet.
- Ferromagnetic substances like iron, nickel, and cobalt are drawn to magnets.
- A magnet’s poles produce a larger magnetic field than its centre does.
- A magnet that is not restrained always faces north and south.
- Magnetic poles with opposite polarities attract and repel one another.
- An object’s distance from another object affects the magnetic force (attraction or repulsion) between them in an inverse manner. When two items are close together, a greater force is exerted.
In daily life, science, and technology, magnets are employed extensively. Hence, we can say that it is not an easy task for students to write a detailed assignment on magnetism. Therefore, various assignment help for students is available online to provide assignment help with magnetism topics online.
