How Magnets WorkAlignment of the outer valence electron orbitals in iron. Every atom in iron has a north side and a south side. If they are all aligned, the entire piece of metal will have a north side and a south side, and it is therefore magnetic. The outer orbitals have only one electron and their motion in the circular path gives rise to a central force through the center of the orbital whose direction is based to the right hand curve rule. And its this force that either expels or attracts a magnet towards other iron materials.

Note: polarity of magnetic dipoles is described as north and south. polarity of electric dipoles is +/-.

To remain a magnet it has to be made out of steel as steel makes a permanent magnet.


Why aren't all magnets magnetic?

A magnet is by definition magnetic. What was a magnet may now be simply a piece of steel or iron, since losing its magnetism makes it not a magnet anymore. An electromagnet is only magnetic when it has current running through it, and is not magnetic when turned off.


Why do magnetic materials attract by the magnet?

The magnet will induce magnetism in the magnetic material. That is, the magnetic field of the other magnet will temporarily convert the magnetic material into a magnet.

How does a magnet and voice coil work in a loudspeaker?

The coil has electricity applied to it by the amplifier. This makes it an electromagnet. It reacts with the static magnetic field of the magnet and moves the attached cone as the current varies.The magnet provides the constant magnetic field in which the varying magnetic field of the coil add to or subtracts from. The coil is connected to the speaker which varies according to the total magnetic field.

What is the difference between magnet and magnetic and magnatism?

A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
