went over my head esp the graph

[@kholaahmad835]

Why in the first method to find constant speed did you not use the number of turns multiply by the magnetic fluc

[@bijyetamaharjan9644]

To increase the induced emf, we can increase the number of turns in the coil (?) And the graph of hall voltage to time will look exactly like the graph of magnetic flux to time because mag flux directly prop to mag flux density and hall voltage directly prop to mag flux density so, therefore, hall voltage and mag flux are directly related (?) pls correct me if I'm wrong XD thank you for ur videos!

[@ETphysics]

Yepp increasing N will increase the flux linkage and hence induced emf.

[@imamunji4434]

@@ETphysics are the explanations said above about the hall voltage correct.?

[@teeshajairam5741]

​@@ETphysics can we increase the speed of the coil as well to increase the induced EMF

[@mayankjoshi7316]

@@teeshajairam5741 yes emf = n (dflux linkage / dtime ) speed = ip to time obv distance k thereby more speed = less time, less time = high emf ( inversely proportional) !! Thats what i think
