The neodymium magnet creates a greater amount of current than any other kind of permanent magnet since it is much stronger magnetically. An induced current of electricity in a conductor always, in turn, creates its own ...

But if you put iron into a strong external B field, this will tend to line up all those little domains, and you can magnetize iron this way.

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
