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

thanks

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

i don't get it

ya that's correct thanks
