What is nbg SW(ω) equal to in senior high school physics? ……

N: the number of turns of the coil winding;

B: magnetic field strength;

S: effective area;

ω: angular velocity of coil rotation;

E=BSw sin wt is instantaneous induced electromotive force;

Then Es=BSw is the maximum electromotive force;

E'=BSw/ root number 2 is the effective electromotive force.
