Apparatus and Materials For each student group Electromagnets are used by doctors to remove tiny iron pieces from the eyes of a person (which may have fallen into the eyes accidently). In constructing an electromagnef, which material do you need A. dry cell Electromagnets can be considered as a temporary magnet that functions with the help of an electric current. The magnetic strength of an electromagnet can be easily altered by varying the amount of electric current and its polarity can be changed by varying the direction of the electric current. Think of all of those bits of electrical equipment with some kind of electric motor: The electromagnet is essential to the starter motor. Two uses of electromagnets are: Electromagnets are used in the construction of a large number of devices like electric bells, loudspeakers, electric motors, electric fans, etc. In the home, by far the most common use of electromagnets is in electric motors. WebElectromagnets of all shapes and sizes can be found doing useful jobs in machinery such as buzzers, bells and relays. Electromagnets are used by doctors to remove tiny iron pieces from the eyes of a person (which may have fallen into the eyes accidently). Which activity can be done with the use of an electromagnet? In the home, by far the most common use of electromagnets is in electric motors. A simple motor also reinforces the importance of closed circuits. Vocabulary - use the blue physical science textbook to define the following words Electric Force: Magnetic Force: Electromagnet: Electromagnetism: Use pgs. Uses of Electromagnets Electromagnets are used in Electrical machines like generators, motors, transformers. Most of the electric appliances used in the home use electromagnetism as the basic working principle. Some electromagnet uses in the home include an electric fan, electric doorbell, induction cooker, magnetic locks, etc. In an electric fan, the electromagnetic induction keeps the motor rotating on and on making the blade of the fan to rotate.
