Question

A coil of copper wire is pulled in a magnetic field with a constant field with a constant velocity. If its ohmic resistance is decreased then:
1)It is easier to pull
2)It cannot be pulled
3)It is difficult to pull it
4)it's emf is increased
Only Write Down Explanation ??Plz

Answer 1

Answer:

hope it helps you dear this answer

Answer 2

According to Ohm.s law

Current    $I=\frac{V}{R}$

So, increase in resistance causes decrease in current. The decrease in current makes it easier to pull the brass wire coil.

Hence, A coil of copper wire is pulled in a magnetic field with a constant field with a constant velocity. If its ohmic resistance is decreased then

1)It is easier to pull
