Calculate the Quantity that flows through a resistance of 200 oams connected to a spiral with a resistance of 400 oams and has 100 rolls rolled around a would stick with a radius of 2 cm if its mangetic field was reduced suddenly from 36Pi X 10^-4 tesla to 0 tesla and is parallel to the stick?I solved it be saying that by calculating Delta Fluxwhich is (-36Pi *10^-4)*(.02)Pi=7.1*10^-4and while
voltage=number of rolls *Delta(flux)/Delta(time)then
voltage*Delta(time)=Number of rolls*Delta(Flux)
V*D(t)=100*7.1*10^-4V=Current*Resistance
V=Delta(Charge)*R/Delta(t)
V*Delta(t)=Delta(C)*R
Delta(C)*600=100*7.1*10^-4

 voltage=number of rolls *Delta(flux)/Delta(time)then 
voltage*Delta(time)=Number of rolls*Delta(Flux)
V*D(t)=100*7.1*10^-4V=Current*Resistance
V=Delta(Charge)*R/Delta(t)
V*Delta(t)=Delta(C)*R
Delta(C)*600=100*7.1*10^-4
