Electro-magnetism

A magnetic insulator shield magnetic fields, and do not let magnetism affect objects on the other side of the material. Is the same materials both good electrical insulators and magnetic insulators? Compare both the electrical and magnetic insulating ability...

In this science experiment, you will use the power of electric current to make a thin wire coil behave in a mysterious way. When current is passed along a conductor, the conductor behaves like a magnet, especially if the...

With this device messages could be sent over a far distance instantly and this was only the starting block for the modern communication devices we use today! In this science experiment we will be re-creating that means of communicating...

In this science experiment you will be learning more about the relationship between electrical current and magnetism by making your own electro-magnet. You will be amazed with how many everyday devices use electromagnets to function, for example: radios, vacuum...

In this science experiment we will be learning more about the relationship between electricity, electrical current, magnets and the laws of magnetism. The connection between electric current and magnetism is very important because as a result electric motors and...

Michael Faraday, an English scientist, accidentally discovered that instead of creating magnetism in a conductor through which electricity flows, the reverse is also possible in that electrical current can be generated by passing magnets against a conductor!
