Detailed explanation-1: -Magnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will become a magnet too. It has become magnetized .

Detailed explanation-2: -Magnetism is the force exerted by magnets when they attract or repel each other.

Detailed explanation-3: -A magnet is surrounded by a magnetic field which pushes or pulls other magnets and things made of iron, nickel or cobalt that are located within it. (Because its interior acts like a magnet, the Earth is surrounded by a magnetic field that affects things made of magnetic material, such as compasses).

Detailed explanation-4: -Magnetism is the force of attraction or repulsion between substances made of certain materials, such as iron, nickel, cobalt, and steel. The force of magnetism, simply put, is due to the motion of electric charges. Magnets are present in most electronic devices. In fact, anything that has a motor uses a magnet.

Detailed explanation-5: -The force which a magnet exerts on iron and steel is called the magnetic field.
