A conducting wheel having 12 spokes out of which 7 are conducting and 5 are of non-conducting material is rotated with constant angular velocity ω about its own axis in a uniform magnetic field B whose direction coincides with that of the axis of wheel. The radius of wheel is R. The emf induced between the centre and periphery of the wheel is
  • a)
    Zero
  • b)
    BωR2 
  • c)
    BωR2 /2
  • d)
    7BωR2 /2
Correct answer is option 'C'. Can you explain this answer?

A conducting wheel having 12 spokes out of which 7 are conducting and ...
We know for each spoke the emf induced will be
= 1/2 BwR²

since all the spokes are parallel to each other, so the total emf will be same as of one spoke.(because in parallel connection current gets distributed but the emf remains same in all)

The standard formula is E= 0.5*B*R*W(square) B is magnetic field, r is radius, w is angular speed Since there is no effect of number of spokes present in the wheel hence the formula remains the same!
