Question

A bulb can be lighted using a strong barmagnet and a coil of insulated copper wire. Define the phenomenon behind this

Answer 1

Electromagnetic induction

Answer 2

The phenomenon is known as the electromagnetic induction.

• Electromagnetic induction is just the opposite thing than the electromagnetism.

• In the electromagnetic induction magnetic a stationary magnetic field helps to produce electrical charge through a rotating inductor present in it's magnetic field.

• Here, magnetic field is converted into electrical field as which is opposite than the electromagnetism. In electromagnetism electrical field is converted into magnetic field.

• This phenomenon of electromagnetic induction is also used in the electricity producing dynamo.
