How Do Magnets Attract?

One of the mysteries that fill our childhood is how the magnets work and why certain things are attracted to magnets while others are not. Here in this short article, we will discuss the reasons behind this. As we have studied in earlier science that every atom has electrons these electrons are revolving in their orbits. Some electrons are unpaired within the atom but not all such electrons can exhibit magnetic behavior. These unpaired electrons should interact with each other which will eventually result in particular electrons alignment and it is due to this particular alignment that certain substances are attracted by the magnet while others are not.

Every magnet is surrounded by it's magnetic field which is formed by the movement of electrons. The hyperactivity of these electrons gives magnets their ability to attract and repel.  That's how electromagnets work; when the electric current passes through the wire, it generates a magnetic field around itself which will last as long as the current flow through the wire. Unlike the magnet which has permanent north and south poles, the electromagnet does not have permanent poles rather it's polarity can be reversed by changing the direction of current flow through the electric wire.
