... 4. Wrap insulating wire in a tight coil around the length of a large iron nail or bolt so that there are at least several layers. Leave a few inches of loose wire on either end and strip the insulation off of the loose ends using wire strippers or scissors. 5. Using alligator clips, attach the e ...

Electricity and Magnetism Summary Notes
... When electricity flows through a wire the wire can get hot. This can be dangerous as it can create an electrical fire. It is also used in electric fires, irons, stoves and light bulbs. As electricity can be dangerous we need a method to ensure that we stay safe even if something goes wrong. Also som ...

... the electric current the dynamo produces. In this generator, however, a strong magnet remains stationary and the coil of wire spins round next to it, so a similar voltage is set up across the coil’s ends. It doesn’t matter which one moves, the magnet or the coil. If it is the coil, sliding contacts ...
