What is magnetism
1 answer
Magnetism is a natural phenomenon that arises from the movement of charged particles, usually electrons, within magnetic materials such as iron, cobalt, and nickel. It is the property of an object that allows it to produce an attractive or repulsive force on another object that has a magnetic field. Magnetism can be temporary or permanent, and its strength is measured in units called teslas or gauss. It is utilized in various applications, such as electric motors, generators, speakers, magnetic resonance imaging (MRI), and many others.
