In Figure (a)
In Figure a, switch S has been closed on A long enough to establish a steady current in the inductor of inductance L 1 = 5.00 mH and the resistor of resistance R 1 = 25.0 Ω .Similarly, in Figure b, switch S has been closed on A long enough to establish a steady current in the inductor of inductance L 2 = 3.00 mH and the resistor of resistance R 2 = 30.0 Ω. The ratio Φ 02 /Φ 01 of the magnetic flux through a turn in inductor 2 to that in inductor 1 is 1.50. At time t = 0, the two switches are closed on B. At what time t is the flux through a turn in the two inductors equal?

In Figure (a), two concentric coils, lying in the same plane, carry currents in opposite direction. The current in the larger coil 1 is fixed. Current i2 in coil 2 can be varied. Figure (b) gives the net magnetic moment of the two-coil system as a function of i2. The vertical axis scale is set by μ≠t,s=2.0×10−5A.m2, and the horizontal axis scale is set by i2s=10.0mA. If the current in coil 2 is then reversed, what is the magnitude of the net magnetic moment of the two-coil system when i2 = 7.0 m A?
