[QUOTE="welshwizard, post: 186, member: 3"] [B]EXERCISE 10:[/B] 1/. Describe what happens when a magnet is moved towards a coil. 2/. What would happen if the magnet in Q.1, moved towards the coil faster? 3/. What do you call the current that is produced by the movement of a magnet relativeto a coil? 4/. Name the three parts of a transformer. 5/. A transformer has 200 turns on the primary and 480 turns on the secondary. If the required secondary voltage is 240 V, what is the supply voltage? 6/. If a transformer has a secondary current of 1 A, and primary and secondary voltages of 100 V and 24 V resectively, what will be it's primary current? 7/. A conductor 350 mm long, cuts a magnetic filed of flux density 0.8 T. What will be the induced emf when the conductor is travelling at 5 ms [/QUOTE]
