Question

plz understand the ques first...and then plz give reason what will happen in 3rd case ...why ?give reason ​

Answer 1

1)when current in rod ab is increased the displacement of rod is increased as force acting on rod is directly proportional to the current flowing through it on increasing the current, force on the conductor increases.

2) if a stronger horse shoe magnet is used then the strenght of the magnetic field will increase leading to greater force on the rod due to this the displacement of rod will increase.

3) displacemnt of conductor is increased with an increase in the length of the conductor on increasing the length more force will act on the conductor.

plz mark as brainliest if it helped.
