Magnets and Motor Final Project- ELECTROMAGNETS



Advantages

The electromagnet has led to iniventions breakthrought in energy and medicine. The electromagnet is clean energy it does not polute the environment. It does not produce radioation so it is much safer then nucler power. Electromagnets can be turned on and off unlike other magnets that are on all the time.

disadvantages electromagnets caan cause twiching because the current can flow the same path as nerves. They only work at sertan tempechers because it over heats very easy. Some people are scared of the radio frecuncy.

History William sturgeon invented the electromagnet in 1825. in 1830 Joseph Henry made a better electromagnet by wrapping more wire around a iron horse shoe and it could hold 1 ton The first electromagnets was a iron horse shoe with 18 wraps of wire

personal experiences

The bolt on the switch gets very hot. The more battires that are put in the circut the stronger it gets. Wires are wrapped around an iron bolt to make magnetisum.
