- Some more induction related demonstrations:
- 27:16 to 31:25 Induced emf in one single loop of different size/shape loop around a solenoid.
- 31:25 to 33:40 Induced emf in one single loop vs. the induced emf in a 3-loop coil around a solenoid, and the idea behind transformers.
- 33:40 to end Induced emf and induced electric field are not conservative – this is something very unintuitive, and as Professor Lewin said, “It will blow your mind”!

However, you can still watch this video at https://www.youtube.com/watch?v=FUUMCT7FjaI . I place this link here because I cannot find anything with equivalent or better quality (in terms of physics content). I do not condone Lewin's terrible behavior. For your safety, students should not contact Lewin in any way.)
