Magentic materials are mainly of three types. 1) Diamagnetic materials 2) Paramagnetic materials 3) Ferromagnetic materials Diamagnetic meterials are those that do not have megnetic property. Para magnets can be used as temporary magnets Ferro magnetic materials are tose which are permanent magnets. The magnets made from magnets that easily lose their magnetis catue are paramagnets.

Magnetism
An electro magnet proves that Electricity and Magnetism always co-exist in nature
Both are magnetic.
Magnetic forces are produced by the motion of charged particles such as electrons. Magnetism is one of the fundamental forces of nature.

Magnetism
The known magnetism in a bar magnet is electromagnetism.
The weight of a magnet does not directly affect its strength. The strength of a magnet is determined by its magnetic material, shape, and how it is magnetized. A heavier magnet may have more material in it, which could potentially make it stronger if the material used has high magnetic properties.
The simple answer is, it becomes weaker and weaker and eventually looses its magnetism. In a permanent magnet magnetic domains within the material are nearly all oriented in the same direction, amplifying the magnetic effect. As one heats this material, the domains become more random. When heated sufficiently high, to the CURIE POINT, the material loses all of its magnetism. If the material is then cooled in the presence of a magnetic field, it will be re-magnetized. In some materials, heating to temperatures below the curie point will result in temporary loss of magnetism which will be regained as the material cools (reversible losses). Heating to temperatures below the curie point may also cause irreversible losses, ie, the magnetism does not return to its previous strength when cooled.
A temporary magnet is a material that can be easily magnetized but loses its magnetization quickly when the external magnetic field is removed. These types of magnets are often made from soft magnetic materials such as iron or steel. Temporary magnets are commonly used in applications where magnetism is required momentarily or can be easily changed.
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
The process of making a material into a magnet is called magnetization. This involves aligning the magnetic domains within the material, which creates a net magnetic field. This can be achieved through methods such as rubbing a material with a magnet or applying an external magnetic field.

The real test for magnetism is to see if a material can attract other materials like iron or steel. This can be done by bringing a magnet close to the material and observing if there is an attraction or repulsion. Alternatively, one can use a compass to see if the material can influence its direction.
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the permanent magnet.
