Is magnet a conductor of electricity?
That would depend on what material the magnet is made of, not the fact that it is a magnet.
- metal (e.g. iron, alnico, ndfeb) yes, it is a conductor
- nonmetal (e.g. magnetite, ferrite ceramic, plastic refrigerator magnet) no, it is an insulator
A magnet has a magnetic field associated with it. The field could be said to "stand around" the magnet. If this field is "swept" across a conductor, the moving magnetic field will induce a voltage in the conductor. And, if conditions permit it, a current will flow in response to the "pressure" of the induced voltage. This is the principle of electromagnetic induction, and it is what causes a magnet to produce electricity in a…
Principle is electromagmnetism. When a conductor cuts magnetic field electricity is induced in the conductor (Fixed magnet). When a magnet is moved near a conductor electricity is generated in the conductor (Fixed conductor). In speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated…
Assuming you mean electrical conductor / insulator, most bar magnets are made of solid metal, either iron, neodymium or an alloy of aluminium nickel and cobalt, so they conduct electricity. There is one type of magnet called a ferrite magnet which does not conduct electricity - they are the type often found in loudspeakers.
When a magnet is moved near an electrical conductor (usually a coil of wire), it excites electrons in the conductor. This happens because the magnet is polarized, meaning one side has a negative and one a positive charge, and this charge attracts or repels electrons in the conductor. The motion of the electrons is electricity.
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magnetic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.
Some magnets conduct electricity quite well. Others are pretty good insulators. If the magnet is made from metal, chances are that it will be a pretty good electrical conductor. If it is a ceramic magnet or one where magnetic particles are suspended in a non-conductive medium (like those flexible rubber fridge magnets that businesses like to distribute) then the magnet will usually be a very poor electrical conductor.
When any material moves through a magnetic field (for example, close to a magnet), a voltage is induced in the material. If the material is a good conductor, and is properly connected, a current can be derived from this. Moving the conductor through the magnetic field requires work (due to the magnetic field of the moving conductor itself); thus, mechanical energy is converted into electrical energy, and energy conservation is not violated.
