What magnetic flux links its turns

Reference no: EM13563058

A circular coil has a 20.0 cmradius and consists of 30.0 closelywound turns of wire. An externally produced magnetic field of2.60 mT is perpendicular to the coil.

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

(b) When the current in the coil is 2.40 A in a certain direction, the net fluxthrough the coil is found to vanish. What is the inductance of the coil?
