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

Using more wire loops
Using opposite pole of magnet
Using a weaker magnet
Moving the solenoid slower

Respuesta :

Using more wire loops

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

[tex]e = \frac{d\phi }{dt}[/tex]

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

[tex]e = N\frac{d\phi }{dt}[/tex]

Induced current is given by

i [tex]i = \frac{e }{R}[/tex]

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