A single loop of wire with an area of 2.40 x 10-3 m2 exists in the xy-plane in a magnetic field with a magnetic field of 2.60 T in the +z direction at a time of t = 3.00s. This magnetic field may be changing in time. (The surface of the loop is perpendicular to the direction of the magnetic field.) If an induced emf of 9.00 V exists in the current at a time t = 3.00 s Driving the current clockwise as seen from a point with a positive z value, then what is the magnetic field strength at t = 5.00 s? (23.2, 23.3)

Explanation / Answer

V = A*dB/dt

so

dB/dt =9/(2.4*10^-3)

=3750 T/s ( in +z direction)

meg field at 5 sec

= 2.6+3750(5-3)

= 7502.6 T
