Introduction to Hard Magnets
Hard magnets, also known as permanent magnets, are materials that can retain their magnetic properties over a long period of time. They are made from ferromagnetic materials such as iron, nickel, and cobalt, which have high coercivity, meaning they require a large magnetic field to demagnetize them. Hard magnets are widely used in various industries, including electronics, automotive, energy, and healthcare, due to their ability to generate a strong and stable magnetic field.
