One Application of Magnetic Fields in Household Appliances
One thing that uses magnetic fields is the electric motor, which is used in many household appliances, such as electric fans, microwave ovens, and other small appliances. In this instance the electric motor has an electric current, giving it also this magnetic field.
An electric motor converts electricity into mechanical motion.
Most electric motors work by electromagnetism, but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying element is subjected to a magnetic field. In a cylindrical motor, the rotor rotates because a torque is developed when this force is applied at a given distance from the axis of the rotor.
Most electromagnetic motors are rotary, but linear types also exist. In a rotary motor, the rotating part (usually on the inside) is called the rotor, and the stationary part is called the stator. The motor contains electromagnets that are wound on a frame.…
