Q
Q: In an AC generator, the induced EMF is maximum when the coil is positioned at what angle to the magnetic field?
Solution: In an AC generator, the induced EMF is maximum when the coil is positioned at 90 degrees to the magnetic field, as this is when the rate of change of magnetic flux is greatest.
Steps: 6
Step 1: Understand that an AC generator uses a coil of wire and a magnetic field to produce electricity.
Step 2: Know that the position of the coil relative to the magnetic field affects the induced electromotive force (EMF).
Step 3: Remember that the angle between the coil and the magnetic field is important.
Step 4: Realize that when the coil is at 0 degrees (parallel to the magnetic field), the induced EMF is zero.
Step 5: Understand that when the coil is at 90 degrees (perpendicular to the magnetic field), the induced EMF is at its maximum.
Step 6: Conclude that the maximum induced EMF occurs at 90 degrees to the magnetic field.
