Magnetism Study Guide
... Magnetic fields – are the places where a magnet’s effects can be felt – exist around all magnets. You can show where a magnet’s field is by using magnetic filings: small bits of magnetic material that are attracted to the magnet’s force. Be sure you can look at the magnetic field of a magnet and d ...

The Magnetic Field Attraction and Repulsion
... When there is current through a conductor, it produces an electromagnetic field around the conductor. The right-hand rule can be used to establish the direction of the electromagnetic lines of force around a conductor. An electromagnet is basically a coil of wire around a magnetic core. When a condu ...

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.
