Question

Circular Coils and Flux A circular coil has a10.3 cm radius and consists of44.0 closely wound turns of wire. Anexternally produced magnetic field of 3.00mT is perpendicular to the coil. (a) If no current is in the coil, what magneticflux links its turns?
1 Wb
(b) When the current in the coil is 2.05 Ain a certain direction, the net flux through the coil is found tovanish. What is the inductance of the coil?
2 H (a) If no current is in the coil, what magneticflux links its turns?
