$7.$ Look back at the wires in Problem $6$a$).$ Let$$s say that the left wire carries $2$ A of current, the right wire carries

$5$ A$.$ The wires are $0\mathrm{.}25$ m apart and are both $3$ m long.

a$.$ What is the magnitude of the magnetic field that the left wire creates at the right wire$$s location?

b$.$ Use your answer from part a$)$ to calculate the magnitude of the magnetic force on the right wire from the left

wire.
