# Wire and loop#

The inifinite, straight wire shown in the figure carries a current $$I_1$$. The rectangular loop, whose long sides are parallel to the wire, carries a current $$I_2$$.

## Part 1#

Find an expression for the magnitude of the force on the rectangular loop due to the magnetic field of the wire.

You may copy and paste the Greek character Î¼0 into you symbolic expression. Use pi to represent Ï.

## Part 2#

What is the direction of the net force on the rectangular loop due to the magnetic field of the wire?
