A conducting wire is bent in the form of a square of side 8 cm and is placed in a region of magnetic field of 0.05 T, such that the plane of coil is perpendicular to the magnetic field. If the side of square starts decreasing at a rate of 10^(-3) m s^(-1) , what will be the emf induced in the coil when the area of coil is reduced to just half?

A coil is rotated with constant angular speed in a uniform magnetic field about an axis that is perpendicular to the field. Tell, with reason, if the following statement is true– “The emf induced in the coil is maximum at the instant the magnetic flux through the coil is zero”.

An emf induced in a coil rotating in a uniform magnetic field is given by

A rectangular coil (0.5 m xx 0.4m) has a resistance of 5Omega . The coil is placed in a uniform magnetic induction of 0.05 T perpendicular to the place of the coil. If the magnetic induction is uniformly reduced to zero in 5 xx 10^-3s , find the current induced in the coil
