Why does charge flow through some materials easier than other (what makes conductors conductors)
Amount of free electrons, more free electrons means easier to transport charge

Dropping a permanent magnet on top of an aluminum plate results in
eddy currents. Induces a current in aluminum. This current creates its own magnetic field that opposes the motion of the block falling.
