It can be turned on and off.
The Poles of an Electromagnet can even be reversed by reversing the flow of electricity.
They are used in MRI machines and Scrap yards so they can pick up heavy Scrap Metal.
You can change the strength by changing the amount of electric current.
Electromagnets are stronger than normal magnets]]> 2018-11-12 12:23:57 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213193 george_taylor1 https://padlet.com/bn18128/4af2nc81jsyf/wish/303213224 The poles of an electromagnet can be reversed by reversing the electricity]]> 2018-11-12 12:24:02 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213224 Fin_D_gherkin https://padlet.com/bn18128/4af2nc81jsyf/wish/303213235 The strenght can be changed by how much power is in putted to it 🙂]]> 2018-11-12 12:24:04 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213235 george_taylor1 https://padlet.com/bn18128/4af2nc81jsyf/wish/303213506 Electromagnets can magnetise metals permanently ]]> 2018-11-12 12:24:52 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213506 Fin_D_gherkin https://padlet.com/bn18128/4af2nc81jsyf/wish/303213509 The poles can be reversed by reversing the electric current 🙂]]> 2018-11-12 12:24:52 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213509 finley_gould https://padlet.com/bn18128/4af2nc81jsyf/wish/303213573 An electromagnet is a magnet that runs on electricity.

-can be easily changed by the ammount of current that flows through it
-magnetic field is produced by an elecrical current
-the poles of the magnet can be reversed by reversing the flow of electricity 
-made of soft metal core
-used for high disk drives, speakers, motors and generators
-when electric current flows in a wire it creates a magnetic field around the wire. This effect can be used to make a electromagnet. ]]> 2018-11-12 12:26:11 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213924 noah_cardew https://padlet.com/bn18128/4af2nc81jsyf/wish/303213932 Electromagnets are used electrical devices including loud speakers, motors,generators and mri machines]]> 2018-11-12 12:26:13 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213932 finley_gould https://padlet.com/bn18128/4af2nc81jsyf/wish/303213962 An electromagnet is made of a length of sire turned into a coil and connected to a battery supply.]]> 2018-11-12 12:26:18 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303213962 bn18128 https://padlet.com/bn18128/4af2nc81jsyf/wish/303217079 2018-11-12 12:35:31 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303217079 bn18128 https://padlet.com/bn18128/4af2nc81jsyf/wish/303217840 2018-11-12 12:38:01 UTC https://padlet.com/bn18128/4af2nc81jsyf/wish/303217840
