Circular coils and flux a circular coil has a103 cm radius, Ask an Expert

Academics

Circular Coils and Flux A circular coil has a10.3 cm radius and consists of44.0 closely wound turns of wire. An externally produced magnetic field of 3.00mT is perpendicular to the coil.

1) If no current is in the coil, what magnetic flux links its turns?

2) When the current in the coil is 2.05 Ain a certain direction, the net flux during the coil is found to vanish. What is the inductance of the coil?
