13. Two current-carrying wires cross at right angles.
a. Draw magnetic force vectors on the wires at the points
included with dots.
b. If the wires aren't restrained, how will they behave?
They will rotate

4 A current loop is placed between two bar magnets. Does the loop
move to the right, move to the left, rotate clockwise, rotate
counterclockwise, some combination of these, or none of these?
Explain.

N
S
It rotates counter clockwise. The magnetic field
created by the magnets points to the left
The forces on the loop as shown, tend to
rotate the loop ccw.
. A square current loop is placed in a magnetic field as shown.
a. Does the loop undergo a displacement? If so, is it up, down, left, or right?
It will rotate but it will not undergo
If not, why not?
translational displacement
