Iron core inductance.

Following this logic we arrive at common factor called inductance. The greater the inductance, whether a result of an iron core or increased copper windings yields greater magnetic force per unit of input power.

Suppose we perform Hob's test again with the toy magnet balls. One coil with an iron core the other an air core of greater copper weight then the control coil. Each coil will show the same repulsion advantage of increased magnetic field strength in proportion to their inductance, but what happens when we interrupt the current and measure the output from the free fall of the magnet balls toward the coils?

Lo and behold, the iron core coil will generate more power then the aircore from the addition of the attraction force between the stack of magnet balls and the iron core.
