Question

In physics lab, you hang a wire perpendicular to the magnetic field created by ahorseshoe magnet. You observe that the wire moves downward when you allowcurrent to flow through it. What happens when you reverse the direction of current?a) The wire moves toward the North pole of the magnet.Ob) The wire moves further downward.Oc) The wire moves upward.d) The wire moves toward the South pole of the magnet.

Answer 1

`F=\text{ilBsin}\theta`

current is reversed now

the force is also reversed

that means, the conductor(wire) will move in reverse of the previous direction

means option c
