What You Need To Know About Magnets

We all use magnets in our homes, offices and different spheres of lives, but have hardly thought about their importance. They are made of the materials that have the potential to stimulate magnetic reactions. These reactions are created with the presence of the magnetic field and examples of these materials are copper, iron and steel.
The atoms of the magnetic materials are arranged as units and are given the name of domains. Factually speaking, the domain is the set of some atoms that have the task of acting like a magnet. If these domains are placed against a strong magnetic field, they are made to move in the direction of the magnetic field. The attribute of these domains is that they pull each other and align themselves to become a strong magnet. The concept of the magnet is not a new one and it has been helping us for quite some centuries now. The model of magnetism was innovated by a scientist called William Gilbert as he was the first person to realize that our earth is nothing but a magnet. Later in his life, he discovered that making a magnet is very easy and it requires twisted irons. After William Gilbert, it was another scientist by the name of Hans Christians who discovered that there is a broad connection between electricity and magnetism.

In our modern day world, we have three different kinds of magnets. They are the temporary magnets, permanent magnets and electromagnets.

Those called temporary are the ones that can reduce magnetic reactions when placed in even weaker magnetic fields. But as soon as the magnetic field is removed, they simply lose their reactions. Permalloy and soft iron can be placed in this category.

On the other side, permanent magnets exhibit their magnetic power and properties even after they have been removed from the field or the field has been removed from around it. Examples of this variant are ferrite and alnico. This version is used in the production of magnetic sheeting as well. On the other hand, some electromagnets are made to perform bigger tasks on a massive basis. This version is made by placing the core metal inside a coil of wire that carries an electric current. All of them are used in several kinds of tasks in the modern world such as electric motors and generators. For example, the temporary version is used in telephones and televisions whereas the electro version is used in larger vehicles like Maglev trains. The quality of this train is that it generates without wheels. This kind of train works by using a magnetic reaction that occurs between the tracks and the lower portion of the train.

The last kind is the super magnets, but the good thing about them is that they are very easy to create. Several magnets can be transformed into a powerful magnet. There are several things required in the process of making useful super magnets.
