Electromagnetism

In this topic, we will study the Oersted experiment which established that a current wire acts as a magnet. It also discusses the facts concluded by this experiment with the help of activities and illustrations.

In this topic, we will study the generation of magnetic field due to the electric current in a loop. It explains how flow of the electric current in a circuit can cause the magnetism and also shows the working of a solenoid.

This topic provides a description of magnetic force acting on a current-carrying conductor. It also shows how to calculate the magnetic force of the conductor placed in an uniform magnetic field with some examples.

This topic covers the details of working of DC motor. Here we will learn that the basic principle of the DC motor and also discuss the important components of the DC motor along with their working.

In this topic, we will understand the concept of electromagnetic induction with the help of an activity and illustrative diagrams. It also describes how to use Fleming's right-hand rule for the prediction of direction of current.

This topic explains the concept of electric generator with its classification into alternating and direct current generators. It elaborates the construction and working of A.C. generator with its advantages.

This topic deals with the concepts related to alternating current. It explains the arrangement of winding of primary and secondary coils with a transformer. It also discusses the reasons behind small energy loss.
