Keyword Challenge Your challenge is to make as many words as you can from todays keyword electromagnet How did you do 10 words or more 8 words or more 6 words or more State 2 uses of regular magnets. Concepts Simple sources of electrical power Activity We are going to begin investigating electromagnets Lets seedoesnt electromagnets imply magnets that are somehow run by electricity That means we are going to need a source of electrical power does 70 70 Electromagnets EM4-HVA, EM7-HV D Continuously adjustable poles allow rapid air gap changes to suit individual experiments, assuring magnet versatility D Exceptional field intensities achieved w Intro video. Properties of Magnets. They attract ferromagnetic materials. Iron, nickel, cobalt. They have magnetic poles. Like poles repel. Opposite poles attract. Magnetic Poles. Magnetic Fields. The area . Dampers for Vibration Control. Presenting by,. . JITHIN.K. M-Tech, Machine Design. Roll No: 9. Guided by,. Dr. . K.G.Jolly. H.O.D . Mechanical Dept.. INTRODUCTION. Viscoelastic and fluid film dampers.. 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. . Induction: https://www.brainpop.com/technology/energytechnology/electromagneticinduction/.
