In Figure a two concentric coils lying in the same plane carry currents in opposite directions The current in the larger coil 1 is fixed Current i2 in coil 2 can be varied Figur b gives the net magnetic moment of the two coil system as a function of i2 The vertical axis scale is set by Wnets 1 90 x 10 5A m and the horizontal axis scale is set by i25 8 00 mA 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 6 00 mA Number M O a 2 net 10 5 A m Unet s 0 net s 0 Unit i mA b 195
