A long straight wire is carrying current $I_1$ in $+z$ direction. The $x-y$ plane contains a closed circular loop carrying current $I_2$ and not encircling the straight wire. The force on the loop will be:
Two thin long parallel wires, separated by a distance $d$ carry a current of $I$ $amp$ in the same direction. They will
Write formula for current carrying wire placed in uniform magnetic field.
Two parallel beams of electrons moving in the same direction produce a mutual force
A square loop $ABCD$ carrying a current $i,$ is placed near and coplanar with a long straight conductor $XY$ carrying a current $I,$ the net force on the loop will be
