Magnetism

In this topic, we will discuss the discovery of magnets. We will understand about the magnesia with its various properties. We will learn how it was given the name of the leading stone. We will also study its compound formula.

In this topic, we will study magnet in detail. We will talk about the compound formula, along with some properties of minerals. We will also learn about the definition of magnetic substances with examples.

In this topic, we will talk about the natural and artificial magnets. It describes the definition of both of them. We will learn the names of magnets which have different shapes with the help of figures

This topic explains various properties of magnets. We will understand how to verify them by demonstrations.

In this topic, we will talk about the magnetic field. We will discuss how to create it through the magnetic lines of force. We will understand the representation of the magnetic field through various experiments.

This topic enhances the knowledge on the concept of earth’s magnetism. It discusses how earth behaves like a bar magnet in brief explanation. We will learn the magnetism of earth through the diagram.

With the help of this topic, we will understand how to make magnets in detail. We will discuss what are the methods and things for making it. We will understand this concept through some experiments.

In this topic, we will learn about the electromagnet with the aid of figures. We will understand the working of it and its different shapes. We will understand why steel is not used for making electromagnets.

In this topic, we will learn the process of demagnetisation and storage of magnet. We will learn the various reasons for the destruction of the magnetic properties. We will understand the concept of self demagnetisation and how to avoid it.

Within this topic, we will study the use of magnets in detail. We will talk about some of its important uses. We will learn its uses in large computers, loudspeakers, tape recorders and many other things.
