In This Investigation, I am trying to find out what affects the strength of an electromagnet. I will do this by carrying out two separate experiments. These will involve changing one aspect of each experiment, whilst keeping all others the same.

8th May 2003 Chris Phillips Electro Magnets Coursework Aim: In This Investigation, I am trying to find out what affects the strength of an electromagnet. I will do this by carrying out two separate experiments. These will involve changing one aspect of each experiment, whilst keeping all others the same. Electro-Magnets Electro-Magnets are caused when a current is passed through metal, causing "domains" inside the metal to face in one direction. When a metal is completely non- magnetized, all the domains within the metal cancel each other out, by connecting to each other from head to toe. When the current is passed through the metal, the domains free from their fixed positions and all face in one direction, not connected to one another, and therefore try and connect to domains in other metals close by, causing the magnet to attract another metal (See scientific theory.) Scientific Theory. In a non-magnetic piece of metal, domains...
