Two long parallel wires carry currents of equal magnitude but in opposite directions. These wires are suspended from rod PQ by four chords of same length L as shown in figure . The mass per unit length of the wires

A long straight rigid wire carrying a current is kept co-axially with the current carrying long thin plane which is bent in the form of a circular arc. If the inward current i flows through the plate find the magnetic force acting on the wire.
