A conducting rectangular loop of mass M, resistance R, and dimensions w by ? falls from rest
Question:
A conducting rectangular loop of mass M, resistance R, and dimensions w by ? falls from rest into a magnetic field B as shown in figure. During the time interval before the top edge of the loop reaches the field, the loop approaches a terminal speed vT.
(a) Show that vT = MgR/B2w2
(b) Why is vT proportional to R?
(c) Why is it inversely proportional to B2?
