Induction and Electromagnetism

Front

What type of energy does a generator produce?

Back

Electrical energy is produced by a generator through the conversion of mechanical energy.

Front

What is the role of a galvanometer?

Back

A galvanometer is an instrument used to detect and measure small electric currents.

Front

What happens if the needle on a galvanometer is not moving?

Back

If the needle is not moving, it indicates that there is no electrical current flowing.

Front

What device is used to change the direction of current in an electric motor?

Back

A commutator is responsible for reversing the direction of current in an electric motor.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is electromagnetic induction?

Back

Electromagnetic induction is the process of generating electric current from a changing magnetic field.

Front

What is the function of a motor?

Back

A motor converts electrical energy into mechanical energy.

Front

What is the difference between a generator and a motor?

Back

A generator converts mechanical energy into electrical energy, while a motor converts electrical energy into mechanical energy.

Front

What is a solenoid?

Back

A solenoid is a coil of wire that produces a magnetic field when an electric current passes through it.

Front

What is a ferromagnet?

Back

A ferromagnet is a material that can be magnetized and retains its magnetic properties.
