Browsing: Magnets
Magnets are materials that produce a magnetic field, which invisibly exerts a force on other ferromagnetic materials and affects the path of electrically charged particles. Magnetism itself is a component of the electromagnetic force, one of the fundamental forces of nature. Magnets can be either permanent or temporary. Permanent magnets, such as those made from iron, cobalt, nickel, or alloys like neodymium-iron-boron, retain their magnetic properties over time without external influence. Temporary magnets exhibit magnetic properties only when affected by an external magnetic field. Magnets are widely used in various applications, from household items like refrigerator magnets and electric fan motors to industrial uses in generators, electric motors, and magnetic storage media like hard drives. In medical technology, they are crucial for machines like MRI scanners, and in everyday technology, they are used in things like credit card strips and compasses.
