A
loop of wire has a resistance 362 Ohms and an area of 2.91 m2 . The
wire loop is located in a magnetic field which is perpendicular to
the plane of the loop. The magnetic field has the following time
dependence: B=B0 exp(-b*t) where t is time. b =0.45Hz. The current
is 0.00631 Amps at time 0.79s. Find B0 in units of Tesla. (Note
that both B and B0 are magnitudes i.e. positive.)
