You wish to invent a sparker for lightning gas burners. A 1.5-A current from a battery runsthrough a primary coil. When the switch in this circuit is opened, the current decreases to zero in0.60 ms, thus inducing a voltage in a secondary coil that causes a spark across a 0.50 mm gap.What must the mutual inductance be between the coils if the dielectric strength of the fumesbetween the gap is 2.4 x10 ^ V/m?
