Q. A wheel has three spokes and is in a uniform magnetric field perpendicular to its plane, with the axis of rotation of the wheel parallel to the magrietic field. When the wheel rotates with a uniform angular velocity $\omega$ , the emf induced between the center and rim of the wheel is 'e' . If another wheel having same radius but with six spokes is kept in the same field and rotated with a uniform angular velocity $'\omega/2$, the emf induced, between the center and the rim will be

Electromagnetic Induction

Solution:

e = B $\frac{dA}{dt} = \frac{1}{2} B \omega r^2$
$\therefore $ In every spokes same mrfdeveloped, and cycle spokes is equivalent To parallel combination of cells.
