EMF induced in a coil rotating in a uniform magnetic field will be max...
Explanation:
When a coil rotates in a uniform magnetic field, an EMF is induced in the coil due to the change in magnetic flux linking with the coil. The maximum EMF induced in the coil can be determined by the following factors:
Rate of cutting flux by the coil sides:
- The EMF induced in the coil is directly proportional to the rate of cutting flux by the coil sides.
- The faster the coil rotates, the higher the rate of cutting flux, and hence, the higher the induced EMF.
Flux linking with the coil:
- The EMF induced in the coil is directly proportional to the flux linking with the coil.
- The more the number of magnetic field lines passing through the coil, the higher the induced EMF.
Rate of change of flux linkage:
- The EMF induced in the coil is directly proportional to the rate of change of flux linkage.
- The faster the flux linkage changes, the higher the induced EMF.
None of the above:
- The maximum EMF induced in the coil is obtained when the coil is placed perpendicular to the magnetic field.
- This is because the maximum number of magnetic field lines pass through the coil, and hence, the maximum flux linking with the coil.
- The rate of cutting flux by the coil sides and the rate of change of flux linkage are also maximum in this condition.
- Therefore, option D is the correct answer.
