Solution:
Change in flux takes places only when rotating the coil perpendicularly to its plane. In the remaining three cases change in flux does not takes place so no emf will induce.
A circular coil is placed in a uniform magnetic field. An induced emf can be produced in this coil by
Change in flux takes places only when rotating the coil perpendicularly to its plane. In the remaining three cases change in flux does not takes place so no emf will induce.
