Question

Hi can someone help me What relationship can I make between the number of loops and the current produced, two rings vs four rings?

Answer 1

Given:

The picture of magnetic field lines passing through coil.

To find:

Relationship between the number of loops and the current produced, two rings vs four rings.

Step-by-step explanation:

From Faraday's law of electromagnetic induction we have,

`E=-n(\Delta\phi)/(\Delta t)`

where, E is the emf induced.

n is the number of coil.

The negative sign indicates that the voltage generated is opposite to the cause of the generation which is known as the Lenz's law.

We know Current is directly proportional to the emf generted.Thus, current is directly proportional to the number of coil.

So with the increase in number of coil the current produced will increase.

So if the current produced by two loops is I then the current produced by four loop is 2I.

Conclusion:

Thus the current produced is directly proportional to the number of loops.

The current produced via 4 loop is twice the current produced via 2 loops.
