## Oscillation of a freely suspended magnet in a uniform magnetic field

In this short piece of article, we will discuss the oscillation of a freely suspended bar magnet in a uniform magnetic field. We also show that this oscillation is a simple harmonic in nature and will also derive an expression…

## Tangent galvanometer class 12 – principle, construction, theory, and working

In this article, we will discuss the tangent galvanometer – principle, construction, theory, and its working, so let’s get started… What is tangent galvanometer? Tangent Galvanometer – Tangent galvanometer is a device which is used to measure very small currents.…

## Electromagnet – definition, properties, working, and uses

Every science student knows from his tenth class that when an electric current passes through the wire, a magnetic field is produced in a plane perpendicular to the direction of the current flow. We have learned lots of things from…

## Permanent magnet – definition, types, properties, and uses

There are two main types of magnets, i.e., permanent magnets, and electromagnets. A permanent magnet is called a permanent magnet because it has permanent magnetism. It generates its own persistent magnetic field from the internal structure of the materials itself,…

## What is the difference between a permanent magnet and an electromagnet?

Have you ever played with the magnet which is in the speaker? The magnet that is in the speaker is an example of a permanent magnet because it has its own magnetic field. It has inbuilt magnetic property. It doesn’t…

## Hysteresis loop class 12 | definition, types, applications, and energy losses

It would be very wrong that we talk about the magnetic field and not talk about hysteresis. It is common for all ferromagnetic materials to have the property of hysteresis. But, what is hysteresis? Nothing, It is just a lagging…

## Difference between paramagnetic, diamagnetic, and ferromagnetic materials, class 12

On the basis of the magnetic properties of the materials, they can be divided into five main categories viz. diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic, and antiferromagnetic materials. The basic difference between the diamagnetic, paramagnetic, and ferromagnetic materials is that the diamagnetic materials are feebly…

## Ferromagnetic Materials – Definition, Causes, properties, and applications

There are various types of magnetism in nature viz. paramagnetism, diamagnetism, ferrimagnetism, etc, among these, ferromagnetism is the strongest one. Ferromagnetic materials are materials that exhibit instant net magnetization at the atomic level even in the absence of an external…

## Paramagnetic materials | definition, properties, and examples, class 12

In this article, we will discuss Paramagnetism, and paramagnetic materials, their definition, properties, and class 12, so let’s get started. What is paramagnetism? Paramagnetism is a form of magnetism in which some materials are weakly attracted towards an externally applied magnetic field, and…

## Diamagnetic Materials | Definition, Properties, and Applications, class 12

In this article, we will discuss what are diamagnetic materials? Definition, properties, and its application. So let’s get started… What is diamagnetism? Diamagnetism is the property of all the materials and, it always makes some weak contribution to the materials,…
