Question

When current is passed through a coil of wire, the magnetic lines of force at the center of the coil​

Answer 1

Explanation:

The current passing through a circular coil of two turns produces a magnetic field of 4μT AS ITS CENTER. The coil is then rewound, so as to have four turns and the current passing through it is doubled.
