6.16
· 6.16 describe the generation of electricity by the rotation of a magnet within a coil of wire and of a coil of wire within a magnetic field; also describe the factors which affect the size of the induced voltage
· Magnet rotating near coil
· Coil rotating near magnet
· ac generator 6.16 Practical - model answers
· Connect a hand turned generator to a light bulb. Observe the light bulb when you...
· Rotate the generator slowly The induced voltage decreases
· Rotate the generator quickly The induced voltage increases
3. Increase the strength of the magnet The induced voltage increases
4. Increase the number of turns in the coil The induced voltage increases 6.16 Plenary
· What are the 3 ways that you can increase the size of the current induced in a generator? Answers
