From electromagnetic induction theory, we know that the average emf induced in a conductor, moving through a magnetic fi eld, is given by

e B v sin volt [ ] 1

Where B is the fl ux density of the fi eld (in tesla) is the effective length of conductor (in metre) v is the velocity of the conductor (in metre/s) u is the angle at which the conductor ‘ cuts ’ the lines of magnetic fl ux (in degrees or radians)

i.e. v sin u is the component of velocity at right angles to the fl ux.
