... 1. Separation is easy with a magnet (try it and be amazed!). 2. All magnetism originates in moving electric charges. For an electron there is magnetism associated with its spin about its own axis, with its motion about the nucleus, and with its motion as part of an electric current. In this sense, a ...

Easy Electromagnet Handout (Teacher)
... Electromagnetic Trains: Travellers to Pudong Airport in China can ride at 430 kph on a train with no wheels. Electromagnets lift and propel the train forward, giving riders a smooth ride as the train floats above the magnetic guideway. Scrapmetal Sorting: Electromagnets make it easy to handle scrap ...

Dipoles
... In physics, there are two kinds of dipoles: An electric dipole is a separation of positive and negative charges. The simplest example of this is a pair of electric charges of equal magnitude but opposite sign, separated by some, usually small, distance. A permanent electric dipole is called an elect ...
