Motors Big and Small (1971) [video]

I stumbled across this series some years back. It's truly an excellent demonstration and explanation of how electric motors, both rotating and linear, work, and the principles behind them.

The presenter, Eric Laithwaite, was a British electrical engineer known as "father of the Maglev". Wikipedia bio has more information:

Does anyone have a similar video but about generating electricity on the coils through moving the rotating piece?
