Dear Anoop,
A magnet is any object with a magnetic field. In order for a magnet to attract an object, the object needs to be ferromagnetic. However, magnets can attract each other when the poles are opposite.Magnetic Fields 1. Magnetic fields occur naturally in materials with a certain composition and can also be seen in electrical currents. The strength of a magnetic field is called its magnitude.
Ferromagnetism 2. Ferromagnetism is the process by which certain materials become magnets or have a tendency to be attracted by magnets. Ferromagnetic compounds include iron, cobalt, magnetite, and ferrite. The most common magnets use magnetite.
Attraction 3. Magnetic attraction occurs because of particle alignment. If most particles tend to align in a certain direction, the compound becomes a magnet. Other substances have a high tendency to be magnetized, such as iron.
Electromagnets 4. Electricity also generates a magnetic field, which gains potential when the medium it travels through is coiled. Examples of electromagnetism can be seen in many simple motors.
All the best.
