What is magnetism, diamagnetism and paramagnetism?

[Stalkerfishy]

I need help understanding both of these terms.



I know that diamagnetism is when the valence electrons of the material are paired and repel a magnetic field.
Does that mean it repels like the North side of a magnet to another North side of a magnet?
Or is it they don't attract at all?

Paramagnetism means the material has unpaired electrons,and the magnet attracts the material.
But this isn't as strong as a ferromagnet,right? What makes something ferromagnetic?

Ok so you know how you can magnetize something by putting a magnet near it? How does that happen. What happens to the electrons or whatever so that the material contains magnetic properties? Do the molecules have to be tilted in order to obtain a magnetic field?

Can diamagnetic things have magnetic properties?

What properties do magnetic things have that they wouldn't have if they weren't magnetic?


Please help. This is insanely confusing

Magnetism is a force that is created by the movement of electrons in an object. When these electrons move, they create a magnetic field around the object. This magnetic field can either attract or repel other objects with magnetic properties.

Diamagnetism is a type of magnetism where the material has no permanent magnetic properties. This occurs when all of the valence electrons in the material are paired and therefore, there is no net magnetic moment. This means that when placed in a magnetic field, the material will create its own magnetic field in the opposite direction, causing it to repel the external magnetic field. This repulsion is similar to two north poles of a magnet repelling each other. However, the strength of this repulsion is very weak and is usually only noticeable in very strong magnetic fields.

On the other hand, paramagnetism occurs when a material has unpaired electrons, which means there is a net magnetic moment. This causes the material to be weakly attracted to a magnetic field. The strength of this attraction is not as strong as a ferromagnet, which is a material that has a strong permanent magnetic moment. Ferromagnetism occurs when the material has a specific arrangement of atoms that allows the magnetic moments to align in the same direction, creating a strong magnetic field.

When a material is magnetized by placing a magnet near it, the movement of the electrons in the material aligns with the magnetic field of the magnet. This causes the material to become magnetized and exhibit magnetic properties.

Diamagnetic materials can have magnetic properties, but they are very weak and usually only noticeable in very strong magnetic fields. They do not retain their magnetic properties once the external magnetic field is removed.

Objects with magnetic properties exhibit the ability to attract or repel other magnetic objects, they can be magnetized by an external magnetic field, and they can create their own magnetic field. These properties are unique to magnetic materials and they would not have them if they were not magnetic.
