Question

A current carrying aluminium rod AB is placed in a magnetic field. The direction of

magnetic field is vertically upward. How do you think the displacement of rod AB

will be affected if

a) The current in the rod AB is increased

b) A stronger horse shoe magnet is used

c) Length of the rod AB is increased?​

Answer 1

Answer:

I think all the options are correct

Explanation:

Because

Increase in current is directly proportional to the displacement due to magnetic field

Increase in magnetic field also directly proportional to the displacement occur

Increase in length will also increase the chance of displacement as more magnetic field will act upon it as the current is also in somewhat increased situation.

Answer 2

Answer:

The displacement of the rod AB

Then the rod will be deflected with greater force as the greater force leads to an increase in displacement as well. ... (iii) If the length of the rod AB is increased then the force exerted on the current-carrying conductor will also increase.
