Question:medium

A current of 4 A is passed through a square loop of side 5 cm made of a uniform manganin wire as shown in the figure. The magnetic field at the centre of the loop is

Show Hint

For any closed loop of regular geometric shape made of uniform wire, if current enters at one point and leaves at another point on the loop, the net magnetic field at the center is always zero.
