Question
Electromagnetic induction is defined as the following:
- The process of charging a body
- The process of generating magnetic field due to current passing through, a coil
- Producing induced current in a coil due to relative motion between a magnet and the coil
- The process of rotating a coil of an electric motor
Hint:
Electromagnetic induction is the process of charging a body.
The correct answers are: The process of charging a body, Producing induced current in a coil due to relative motion between a magnet and the coil
Electromagnetic induction is defined as the process of charging a body.
- Electromagnetic induction is done in order to charge a body.
- An emf is thus created with the magnet which is moved closer to the coil of the body.
- This induces an electromagnetic charge.
