Two current carrying wires cross at right angles as indicated in the figure.

Question

If the wires are not restrained, what statement best describes the motion of the wires?

Hint: To help you visualize the situation, draw first the magnetic field that Wire 1 makes at the points shown on Wire 2. Use those magnetic fields and the current of Wire 2 to find the forces on Wire 2. Repeat the same procedure for the magnetic field that Wire 2 makes at the points shown on Wire 1. Use this now to find the forces on Wire 2.


Wire 1 moves out of the page; Wire 2 moves into the page
Wire 1 rotates clockwise; Wire 2 rotates counterclockwise

Wire 1 rotates counterclockwise; Wire 2 rotates clockwise

Wire 1 moves up; Wire 2 moves to the left
Wire 1 moves down; Wire 2 moves to the right

Answer 1

wire 1 has a horizontal current to the left, wire 2 has a vertical current pointing up

Answer 2

Using RHR i got
Wire 1 rotates clockwise; Wire 2 rotates counterclockwise

Answer 3

thats wat i got as well but is that correct

Answer 4

i am not sure. :(

Answer 5

ya that's correct

thanks
