Question
The process of Inducing current in a coil of wire by placing it in a region of changing magnetic field is:
- Electrical effect
- Heating effect of current
- Magnetic effect of current
- Electromagnetic induction
Hint:
Induction is the method of creating current in a conductor by exposing the conductor to a shifting magnetic field.
The correct answer is: Electromagnetic induction
The process of inducing the current flow in a wire by placing it in a region of changing magnetic field is called electromagnetic induction.
- Electromagnetic induction occurs when the coil is get in contact with the magnet.
- The magnet increases the strength of the magnetic field and the flow of current in the coil.
- When a conductor is moved through a magnetic field, current is created because the magnetic lines of force exert a force on the conductor's free electrons, causing them to move.
- The phenomenon of inducing the current flow by placing the magnet in a coil is called electromagnetic induction.
