At the end of yesterday's work a relay was broken, today we were intrigued at the insides of the little black box so we crushed the plastic casing to expose the guts of the relay. Tried to visualize the inside in action, we could see as the solenoid receives power, it produces a magnetic field that attracts a metal button that hangs above it to be pulled down and this action results in the switch being flipped, we even went as far as to unravel a solenoid, the wire must have been 50 feet long which is surprising for how small the solenoid was.
