Magnets
Magnets are objects that produce a magnetic field, which can attract or repel certain materials, such as iron, steel, and nickel. They can be natural, such as lodestone, or man-made, such as electromagnets or permanent magnets.Magnets have a north pole and a south pole, and opposite poles attract while like poles repel each other. The strength of the magnetic field depends on the size and strength of the magnet, as well as the distance between the magnet and the material it is attracting or repelling.Magnets have many practical uses in everyday life, such as in electric motors, generators, magnetic storage devices, and medical imaging machines.
