Two long wires (1 and 2) run parallel to each other with wire 1 suspended directly above wire 2 . The wires (1 and 2) respectively carry currents of
I_(1)=29.0A
and
I_(2)=64.0A
and they both have a weight per unit length of
0.089(N)/(m)
. Determine the distance that wire 1 should be mounted above wire 2 in order for it to be held in place by magnetic repulsion.
?
What physical quantities determine the magnetic force per unit length acting on wire 1? What physical quantities determine the gravitational force per unit length acting on wire 1? mm
