Rectangular loop of wire with dimensions and w is released at t = 0 from rest just above a region in figure. the loop has resistance r, self inductance l, and m

Rectangular loop of wire with dimensions and w is released at t = 0 from rest just above a region in figure. The loop has resistance R, self inductance L, and mass m. Consider the loop during the time suc region. Assume that the self inductance can be ignored but not the resistance, find the current of the loop as W g B=0 B 1 mg 1-expB (B) mg 1-exp mR BI (A) BI mR
