The magnet is a magnet because its molecules are polarized in a particular direction.
When a Magnet is brought near iron then the molecules in it get aligned in the opposite direction. As we all know opposite poles attract the iron gets attracted to it. Iron molecules retain the polarization as long as the magnet is near it. Very high magnetic field can actually attract no magnetic substances.
Experimentally it was seen that a frog was made to levitate under a magnetic field 10,000 times of that of the earth.

You can imagine the iron to have many small magnets inside it.
Normally there small magnets are not aligned so there is no net magnetic field. That is why IRON does not attract.
But when another magnet is brought next to IRON, the small magnets inside get affected and get aligned to produce a net magnetic field. As a result the iron becomes a magnet as long as the smaller magnets inside are under the influence a permanent magnet(that is to say as long as smaller internal magnets are aligned).
When the permanent magnet is removed, to small magnets lose their alignment and once again the iron returns to its normal state.

Inside a piece of iron are small particles which are like magnets themselves, that is they have a north pole and south pole. But they are all scattered in such a way that each particle's north and south poles are facing random directions. When a magnet is brought in it's vicinity then these particles align themselves in a such a way that all north poles face one direction and south poles in the other direction.
N -- S N --S N --S N--S
N -- S N --S N --S N--S
Thus the iron piece becomes a temporary magnet and gets attracted to the magnet.

Nothing happens to tho iron. It is the magnet that attracts the iron. Magnet has a property to attract iron.

Every piece of iron has two poles - north and South. Opposittes attract and likes repel. inside the magnet there are many domains which upon sensing the prescence of an opp. magnetic field nearby, align themselves in one direction, and hence the attraction.

There is an alignment of the electrons (at least the energy that we attribute to electrons) in the iron, allow the parallel arrangement to increase the force sufficiently to become attracted to the magnet, which is already naturally alligned.

The poles of a magnet are not equal in amounts of electrons and protons.
Opposites attract, and when a magnet comes near iron, the protons, or electorns i dunno, pull at the electorns, or protons again i dunno, and thats about it.
Its an unequal amount of protons and electons TRYING to equal themselves out.
