Capacitance of Parallel Plate Capacitor

A long parall...

Question

A long parallel straight conductors carry $i_{1}$ and $i_{2} (i_{1} > i_{2})$ . When the currents are in same direction, the magnetic field at a point midway between the wires is $20 μ T$ . If the direction of $i_{2}$ is reversed, the field becomes $50 μ T .$ The ratio of the current $i_{1} / i_{2}$ is:

A

\frac{5}{2}
