Sample questions
- Q: What is electromagnetic induction?
- A: Electromagnetic induction is the production of an electric current (EMF) in a coil due to a change in the magnetic field (magnetic flux) linked with it.
- Q: Who discovered electromagnetic induction?
- A: Electromagnetic induction was discovered by Michael Faraday.
- Q: When is a current induced in a coil?
- A: A current is induced in a coil whenever there is a change in the magnetic flux linked with it, for example when a magnet is moved towards or away from the coil.
- Q: How can the induced current be increased?
- A: The induced current can be increased by moving the magnet faster, by using a stronger magnet, and by increasing the number of turns in the coil.
- Q: What is an electric generator?
- A: An electric generator is a device that converts mechanical energy into electrical energy. It works on the principle of electromagnetic induction.
