However, due to their abstract nature, students find them hard to understand. Since magnets are used in multiple applications, introducing them to students is quite important. Such substances are called ferromagnetic substances or electromagnets. There are some materials in which the fields of individual atoms align to pass an electric current through them. However, in most cases, the magnetic fields cancel out each other, and the substance as a whole is non-magnetic. In some cases, the weak magnetic forces of individual atoms align and form a strong magnet. However, all substances are made up of billions of atoms. Therefore, each atom behaves as a tiny magnet. These electrons generate a weak magnetic field. Since all materials are made up of atoms, in which electrons orbit around the nucleus of an atom. When a charge essentially an electron moves, it generates current, and a magnetic field around it. The concept of a magnetic field originates from a moving charge. So, we all are surrounded by a world of magnets. Magnets are in your phone, your computer, and even your wallet if you are carrying a credit card.
