In this Veritasium video, Derek explains why solenoids (electromagnets) work. But I have a confusion.
He only explained the case when the solenoid (electromagnet) attracts a charged object ( that is, the cat). But he didn't explain the case when the solenoids (electromagnets) attract uncharged ferromagnetic substances.
What would be the scenario then?
If there's any problem in my question please inform me. Thanks!
