Exploding soda cans with electromagnets in SLOW MOTION ft Joe Hanson

The quarter was melted not squeezed by sending low voltage/high current through the flat surfaces of the ferrous pins. Similar to the way a Weller soldering gun works to heat the tip.While it is true electrons moving generate a magnetic field, the aluminum can is non ferrous and cannot be magnetized to create an electron cascade effect. Aluminum is conductive but electrons must be flowing through it and only while for it to attain magnetic properties. (This means you must apply a direct power/electron source to the can itself) No amount of magnetic field applied to it will induce a magnetic field and subsequent potential electrons or collection thereof. I call bull. Maybe the magnetic field has a similar effect as gravity has on all matter. We still don't understand the correlation between magnetism and gravity. Sparks/heat??? Does the field acting like gravity on non ferrous matter squeeze the can generating molecular friction thereby heat?
