Question

What is the term for producing a current by changing a
magnetic field?

Answer 1

Explanation :

When a coil is placed in changing magnetic field then a current will induced in the coil. The current caused due to changing magnetic field is called as induced current.

Due to changing magnetic field an emf is induced in the coil. Emf is defined as the rate of change of magnetic flux in the coil

This emf then causes induced current in the coil. It is given by :

`I=(emf)/(R)`

Hence, by changing a magnetic field an emf is induced which in turn causes induced current.

Answer 2

I think the answer is induced emf. It is the term used for producing a current by changing a magnetic field. This term is referred to a voltage produced if the magnetic flux through a coil is changed. Hope this answers your question. God bless.
