Welcome to the Official Guide to No Safety in Numbers. A biological bomb has just been discovered in the air ducts of a busy suburban mall. At first nobody knows if it's even life threatening, but then the entire complex is quarantined, people start getting sick, supplies start running low, and there's no way out. This is the ultimate guide to the book that started the series!
So that we can use the computer, watch the television and fans. And other things that need electricity. Electromagnets are used in electrical devices like electric fan, motor, door-bell, electric buzzers, washing machines, etc., whenever strong magnetic fields are needed to be pâ¦roduced, electromagnets are used. These are used in electrically operated relay switches, and in nuclear research laboratories for directing charged particles.
Uses in Home Appliances: Many of our electrical home appliances use electromagnetism as a basic principle of working. If we take an example of an electric fan, the motor works on the principle of electromagnetic induction, which keeps it rotating on and on and thus making the blade hub of the fan to rotate, blowing air. Not restricting to fan, many other appliances use electromagnetism as a basic principle.
