Lesson 5: Intro to Magnet
... child? Great. You should know that we human have known about magnets for thousands of years and we have been using them practically, as compasses, for almost as long. However, we did not know that there is a link between magnet and electricity until recently. We've only really learned how magnetism ...

Magnetism
... By the end of the 2nd grade, students should know that Magnets can be used to make some things move without being touched. By the end of the 5th grade, students should know that Without touching them, a magnet pulls on all things made of iron and either pushes or pulls on other magnets. Withou ...

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.
