Real-life Application of Electromagnetism in Household Appliances

Electromagnetism is extensively utilized in household appliances for various functions. Two common places where electromagnetism is used in household appliances are:

Electric Motors in Kitchen Appliances

Kitchen appliances like microwave ovens, electric mixers, and grinders utilize electromagnetism in their electric motors. These motors operate based on the electromagnetic induction principle, where the electric current’s magnetic field moves the motor components according to the Lorenz force principle. This movement enables the functioning of these kitchen appliances, providing convenience in food preparation.

Alarming Systems with Electrical Bells

Alarming systems in households often incorporate electrical bells that operate using electromagnetism. In these systems, the sound is produced by electromagnetic coils that move a striker against a bell. When the coil is energized, the iron striker is attracted to it, causing it to strike the bell. This process continues until the striker makes contact with the bell, demagnetizing the electromagnet, and the striker returns due to spring tension, creating the alarm sound. This mechanism is commonly used in doorbells and security systems for alerting purposes.

Electromagnetism plays an important role in various real-world applications, from everyday household items to advanced technologies. In our daily lives, electromagnets are extensively used in devices like fans, doorbells, induction cookers, and electric motors. These electromagnets convert electrical signals into magnetism, enabling the operation of numerous appliances.
