a) The current I that must circulate in the coil "B" so that the
flux
in that column is null
b) The inductance for the current in the previous case considering,
air gap
c) The inductance, when IA =0 and without air gap
and with the current IB found in the previous
case
d) The air gap necessary to reduce the inductance by 10%
