When a metal is magnetic, its sea of electrons are alligned at one sidemaking a postive and negative end. These poles can then sttract or repel the sea of electrons in another metal causing it to also become polarized.
n.b. not all electrons retreat to one side, only enough to allow protons to outnumber the electrons left behind. If all the elctrons did move, the protons would repel each other and the metal would push itself apart and it would crumble.

How do you magnetize something made of ironcobalt or nickle?
You can magnetize something made of iron, cobalt, or nickel by exposing it to a magnetic field. This can be done by using a strong permanent magnet or by passing an electric current through the material. The magnetic domains within the material align to create a magnetic field, magnetizing the object.
What does a magnet attract mean?
When we say a magnet attracts something, it means that the magnetic field of the magnet pulls objects made of magnetic material (such as iron or steel) towards it. This attraction is a result of the alignment of magnetic domains in the material being attracted.
How is a permanent magnet made?
The material from which the magnet is to be made is heated so that it is above what is called the curie temperature. The material is then allowed to cool in a magnetic field. The magnetic field can be made by coiling wire and passing an electric current through it.
What is the difference between a magnet and an electromagnet?
A magnet is a material that produces a magnetic field naturally, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
What is used to separate magnetic material from a mixture of other substances?
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.
The magnetic force of a magnet is?
The magnetic force of a magnet is the force that a magnet exerts on another magnet or a magnetic material. It is responsible for attracting or repelling objects with magnetic properties. The strength of the magnetic force depends on the material and shape of the magnet.
How do you permanently magnetize something?
To permanently magnetize something, you can expose it to a strong magnetic field or stroke it repeatedly with a magnet in the same direction. This aligns the magnetic domains within the material, creating a permanent magnet.
Stroking a magnetic material in one direction with a magnet produces a magnet by?
aligning the magnetic domains within the material in the same direction. This creates a magnetic field in the material, making it a magnet itself.
How can you control the magnetic field of a magnet to turn it on and off?
To control the magnetic field of a magnet and turn it on and off, you can use an electromagnet. By passing an electric current through a coil of wire wrapped around a magnetic material, such as iron, you can create a magnetic field. When the current is turned off, the magnetic field disappears, effectively turning the magnet off.
What is the difference between a permanent magnet and an electromagnet?
A permanent magnet is made of material that naturally produces a magnetic field, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
How does a non magnetic material behave when a magnet is placed near?
A non-magnetic material will not be attracted to a magnet and will not exhibit any magnetic properties. It will not stick to the magnet or experience any noticeable changes in its behavior when the magnet is placed near it.
What is the difference between a magnet and magnetic material?
magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\ magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\The magnetic material is any material in which for a short time the domains are alligned in same direction.This material can be anything like iron,etc.The magnet is a steel in which the domains are permanently arranged in same direction by rubbing method.
