There are some ways that he could have improved the deactivation routine, but I thought the most clever thing was that he used a capacitance sensor to activate the magnet the moment the handle was touched. That had to greatly increase the battery life.

The friction coefficient is probably too low for any realistic electromagnet to be strong enough to make it impossible to "slide" out. Just try with a magnet on your fridge door. It's much easier to slide it around than it is to pull it away.
