Question

Which change will cause an increase in the electric current produced through electromagnetic induction?

Answer 1

Using more wire loops

Answer 2

Answer:

using more wire loops.

Explanation:

When there is a change in magnetic flux linked with a coil changes, an emf is induced in the coil. This phenomenon is called electromagnetic induction.

the amount of induced emf developed is

$e = \frac{d\phi }{dt}$

If there are N number of turns in the coil, then induced emf is given by

$e = N\frac{d\phi }{dt}$

Induced current is given by

i $i = \frac{e }{R}$

So, as number of turns increases, the current produced is also increases.
