Physics · Class 12 · CBSE — Electromagnetic Induction
A circular coil expands radially in a region of magnetic field and no electromotive force is produced in the coil. This is because
- the magnetic field is constant.
- the magnetic field is in the same plane as the circular coil and it may or may not vary.
- the magnetic field has a perpendicular (to the plane of the coil) component whose magnitude is decreasing suitably.
both (b) and (c).
Answer
