What happens if you put a piece of iron next to a magnet?

If you bring a magnet is brought nearby, the domains of the iron nail will align in such a way that, the north pole of iron domains will face the south pole of the magnet, and visa versa. When you remove the magnet, the nail becomes permanent magnet for a while. Iron shaving behave like tiny magnets.

What happens if an iron piece is dropped between two poles of a magnet?

What happens if an iron place is dropped between two poles of strong magnet? Eddy current is produced in it. These eddy currents oppose the motion of the piece of iron. So it falls as it is moving through a viscous liquid.

What happens when you break up a piece of iron magnet in two?

Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

Is iron a permanent magnet?

The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals. There are two types of permanent magnets: those from “hard” magnetic materials and those from “soft” magnetic materials. “Hard” magnetic metals tend to stay magnetized over a long period.

How are nails magnetized?

You can magnetize a nail by touching a magnet to it, by prolonged contact with a magnet, or by building an electromagnet from it.

What is unlike pole?

The two different poles or poles having different charges which attract each other are called like poles. For e. g. North Pole and South Pole. Two same poles or poles having same charges which repel each other are called unlike poles.

What happens when the bar magnet is cut into 4 pieces?

If a bar magnet is broken into four pieces, each piece will behave as an individual magnet because the new poles are formed at the broken ends. If these pieces are broken further, the smaller pieces still remains as individual magnets with two opposite poles.

What is the force of attraction between iron and magnet?

At full contact, the attraction between magnet and iron is the same as between two equal magnets. As the distance increases, however, the attraction between magnet and iron becomes distinctly weaker than the attraction between two equal magnets. This is due to the iron’s low remanence.

What is the difference between attraction between two raw magnets?

Difference regarding attraction. At full contact, the attractive force between a raw magnet and an iron plate is the same as the attractive force between two raw magnets. However, the attraction diminishes with increasing distance quicker than the attraction between two raw magnets (see graph).

What is the difference between ferromagnetic and pot magnets?

For pot magnets the attractive force to iron is stronger than it is to another raw magnet (see FAQ about pot magnets ). Ferromagnetic material (iron, cobalt, nickel) contains microscopically small permanent magnets (molecular magnets). These molecular magnets rotate individually and can be adjusted by external magnetic fields.

Why does iron have a net magnetic moment?

This class of materials, some of the atoms or ions in the material have a net magnetic moment due to unpaired electrons in partially filled orbitals. One of the most important atoms with unpaired electrons is iron.
