Question

Estimate the current in the coil required to produce a flux of 0.5 mWb in the ring.​

Answer 1

Answer:

A flux of 0.5 mWb is produced by a coil of 900 turns wound on a ring with a current of 3 A in it. Calculate (i) the inductance of the coil (ii) the e.m.f. induced in the coil when a current of 5 A is switched off, assuming the current to fall to zero in 1 milli second and (iii) the mutual inductance between the coils, if a second coil of 600 turns is uniformly wound over the first coilRead more on Sarthaks.com - https://www.sarthaks.com/492095/a-flux-of-0-5-mwb-is-produced-by-a-coil-of-900-turns-wound-on-a-ring-with-a-current-of-3-a-in-it
