A bar magnet is moved towards a wire loop suspended as shown in fig .What is the direction of emf. Induced ?

A bar magnet is moved towards a solenoid as shown in Fig. What is the direction of induced current in R ?

The closed loop PQRS is moving into a uniform magnetic field acting at right angles to the plane of the paper as shown in Fig 6.50 state the direction in which the induced current flows in the loop.

A rectangular loop of wire with dimensions shown in figure is coplanar with a long wire carrying current 'I' . The distance between the wire and the left side of the loop is r . The loop is pulled to the right as indicated. What are the directions of the induced current in the loop and the magnetic forces on the left and right sides of the loop when the loop is pulled ?
