I was thinking about a big old junkyard crane that I once saw. The crane used a big magnet to lift cars and put them on train cars. The crane operator could turn the magnet on and off!. What electromagnets are used for?. Electric bells. Loud speakers. Lifting magnets. Energized door locks. Relays. Scrap Yards. Electric Bells. An electric bell is worked by an electromagnet. . When the switch is pushed 'on', current flows through the coil. The coil becomes an electromagnet. It attracts the metal strip. This moves the clanger to hit the bell, but also breaks the circuit. .

Keyword Challenge. Your challenge is to make as many words as you. can from today’s keyword.. electromagnet. How did you do?. 10 words or more. 8 words or more. 6 words or more. State 2 uses of regular magnets. In this unit pupils will. : learn to draw magnetic field lines, showing strength and direction. That an electromagnet can be switched on and off and can have its strength varied, which makes it more useful than a permanent magnet..
