When the plane of the rectangular coil is parallel to the direction of the magnetic field in a dynamo, then
- A. Induced current will be zero
- B. Induced current is maximum
- C. AC is produced.
- D. DC is produced.
Step-by-step solution
When the coil's plane is parallel to the magnetic field, the normal to the coil is perpendicular to the field. The induced emf is proportional to sin(θ), where θ is the angle between the field and the normal. At θ = 90°, sin(θ) = 1, so induced emf and current are maximum.
