What effect does electricity have on magnetism?

Answer 1

A magnet of the usual kind (non-electro magnet), is, to put it simple, a piece of metal. Usually made out of iron. The difference between a regular piece of iron is that the iron molecules inside a magnet has been aligned so that poles (+ & -) are created. This means that if you run electricity through a regular magnet, absolutely nothing will happen apart from that; electricity running through. -when a current is run radially( from center to the edge of one pole) through a strong neodymium disc magnet, it is possible to make a homopolar motor.

Answer 2

Many permanent magnets are based on iron compounds, so are conductive. Why they are magnets, the iron neuclei are individually magnetic and align through something called the Exchange interaction, which allows a closer approach of the nuclei than less comples inter atomic interactions. (just some properties of magnetic materials) The individual iron atoms group into regions called domains, these (in iron compounds) tend to also align, giving a reasonably good permanent magnetic nature for the bar of iron compound. So the individual; magnetic moment of the iron atoms are grouped into an overall alignment in the bar, leading to the permanent bar magnetic property. OK we have a (for example) rod if iron compound that is a bar magnet. If we put a current through it, it may play with the exchange interaction, disaligning the individual domains, reducing the overall magnetic flux intensity of the bar magnet. The current will develop an additional magnetic field which will spiral around the (assumed) length wise orientation of the bar magnet. This will create a superposition of the magnetic flux intensities, and likely work to disrupt the orientations of the magnetic domains within the barmagnet. So two effects, a possible change in the permanent magnetic flux intensity of the bar magnet and a generation of a secondary magnetic flux intensity which will be detectable as a spiral field around the metal object

No, the energy comes from the movement. In a generator, mechanical energy has to be done to keep the magnet moving: the electricity induced in the coils will produce a magnetic field that opposes the direction of movement.

Answer 5

Any current is surrounded by a magnetic field. In general, magnets are caused by electric currents. Even the permanent magnets are caused by electrons circling around their atoms.
