a magnet is plunges into and out of a coil of wire 2 times per second. This induces 5 volts.?

Question

a) if the rate of motion changes so that the magnet is plunged in andn out 6 times per second, what will the be the new induced voltage?
b) if the number odf coils in the wire is doubled from 100 to 200, and the original rate of 2 times per second is kept the same, what will be the new voltage induced?

Answer 1

a) 15 v.
b) 10 v.

Answer 2

do ur ratio 2 is to 5 as 6 is to what? 2 is to 6? mutliply by 3 so 3 x 5 = 15 volts then you definitely choose an induction formulation that contains the shape of turns in ur very last question
