As a general rule nothing, however if you have a ferroelectromagnet, a ferrous core surrounded by a conducting coil, then the atoms align their individual magnetic fields in the direction of the magnetic field created by the coils, causing all the magnetic fields to add together cumulatively, instead of canceling each other out.

It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)
An electro magnet proves that Electricity and Magnetism always co-exist in nature
An electro-magnet can be turned on and off.
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
The Wonderful Electro-Magnet - 1909 was released on: USA: 30 November 1909
An electro magnet!
Electro-Magnet
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
