An AC generator spins a magnet inside a loop of wire to generate an induced current. Which of the following changes would cause
the amount of induced current to increase? Group of answer choices a) None of these would increase the induced current. b) Spinning the magnet faster. c) Using a stronger magnet and spinning the magnet faster would both increase the induced current.d) Using a stronger magnet.
The induced current is related to the rate of change of the magnetic flux in a loop wired, so adding a strong magnet will increase the magnetic flux, and if we increase the spinning we'll increase the change of rate, so both induced a bigger current, so b,c, and d are also correct, but c will show better results.
1. Changing voltage increases the current. 2. Adding more lightbulbs increase the resistance and the light bulbs become dimmer as the current has to be shared. 3. Yes its constant.
Straw polls are considered to be a form of biased sampling. An example of a straw poll is an unofficial vote like who you would like to be the President without actually casting your ballot.
