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.

C.

Explanation:

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.

d. air pressure decreases as altitude increases.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
