... 2. Show students the materials they have to work with and have them write a hypothesis like: If I test different substances, then some will be attracted to the magnet and some will not. Or: If I put two magnets together, then they will be twice as strong as one. Or: If I place magnets together and t ...

... Electricity produces movement if coils of wire carrying current are placed near a magnet. When like poles of the magnet and the current-carrying coils of wire (which act like a magnet) face each other, they repel each other and cause movement. This is the basis of an electric motor. ...

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.
