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?
