Scott Lang (scotty7129) Ed Leedskalnin Experiment (RIP)

Scott Lang was a friend and extensive researcher into Ed Leedskalnin's perspectives and work regarding Magnetic Currents.
Here, scott lifts a large weight with a single tap of a battery.
Normally, like in a Junk Yard, you have the electromagnet turned on with full power at a constant. The magnetism lifts objects.
You turn off the power and the objects fall.

In this arrangement, you only need a single spark to lift the weight. And then reversing polarity with a single spark at the same power to release the weight.
