A coil of area A is placed in the X-Y plane. A uniform magnetic field B_0hati established. The emf induced in the coil is ____

Answer»

clockwise
anticlockwise
zero
depends on the value of A

Solution :The angle between AREA VECTOR `vecA` of the coil and `vecB` is `90^@`. So the flux linked with the coil
`phi=AB cos 90^@`
`therefore phi=0`
`therefore` INDUCED emf `epsilon=0`
