MY NOTES
ASK YOUR TEACHER
As shown below, a wire loop is immersed in a B-field (the direction of the field is shown in the diagram). The loop shrinks from a radius of 77 cm to a radius of 3.2 cm in 0.1 s and
as a result a 8.2 V voltage & a 5 A current are induced. Determine the magnitude of the B-field & the loop's resistance.
