Can unmagnetized steel be magnetized? Yes, all that is necessary is to line up the free electrons in all the atoms in a sample of steel or iron in the same direction.

One way of magnetizing steel is to wrap the electric wire around the steel multiple times and then run a current through the wire.

This will create an electromagnet.

The steel will remain somewhat magnetized after being in the electromagnetic field.

A moving electric current creates a magnetic field according to the left-hand rule.

The fingers of the left hand represent the moving electrons and the thumb indicates the direction of the magnet field created by the moving electrons.

A piece of steel or iron can be “stroked” with a strong magnet.

Repeated stroking in the same direction will orientate the movement of the electrons in the atoms so that the magnetic field of all ( most) of the atoms are facing the same direction.

This can also be accomplished by placing a piece of steel or iron is a strong magnetic field and leaving it there for a period of time.

( note it is easier to magnetize a piece of soft iron than hardened steel. The harder the steel the harder it is to magnetize it.)

Iron Fe number 26 has 8 valance electrons. These valance electrons are in the 4s and 3 d orbitals. # 4s^2 3 d^6 #There are five 3 d orbitals.

The 4s and 1 3d orbital have two electrons one with a positive spin and one with a negative spin which cancels each other out.

There are four 3 d orbitals that have only one electron.

If all four have the same spin ( either positive or negative) this creates a magnetic field due to the movement of the electrons.

If the magnetic fields created most of the atoms are pointing the same direction the piece of Ferrous material ( steel or iron) will be magnetic.

How to Magnetize & Demagnetize Metal

Magnetization is possible only with iron or iron alloys, such as steel. Screwdrivers are commonly magnetized this way to attract screws.

Magnetizing metal involves lining up the positively and negatively charged particles within the metal to create a stronger attraction with oppositely charged metal objects.

You use a magnet to do this.

Opposite ends of a magnet have densely packed, and oppositely charged, particles that attract particles in other metals.

These particles are strong enough that, over time, they can line up the particles in another metal in the same manner of its own particles.

Magnetization is possible only with iron or iron alloys, such as steel.

Screwdrivers are commonly magnetized this way to attract screws.

Magnetizing

Place the magnet at one end of the piece of metal.

The magnet must make as much contact with the metal as possible.
