An electron moves on a straight line path  as shown. The abcd is a coil adjacent to the path of electron.

What will be the direction of current if any, induced in the coil?

A long solenoid has 1000 turns. When a current of  flows through it, the magnetic flux linked with each turn of the solenoid is . The self inductance of the solenoid is : 

A long solenoid of diameter  has  turns per meter. At the centre of the solenoid, a coil of 100 turns and radius  is placed with its axis coinciding with the solenoid axis. The current in the solenoid reduces at a constant rate to  from  in . If the resistance of the coil is . the total charge flowing through the coil during this time is:  

The magnetic potential energy stored in a certain inductor is , when the current in the inductor is . This inductor is of inductance

A 800 turn coil of effective area  is kept perpendicular to a magnetic field . When the plane of the coil is rotated by  around any of its coplanar axis in , the emf induced in the coil will be:

Two conducting circular loops of radii  and  are placed in the same plane with their centres coinciding. If , the mutual inductance  between them will be directly proportional to

A square loop of side and resistance  is placed in a magnetic field of . If the plane of loop is perpendicular to the direction of magnetic field, the magnetic flux through the loop is:

A big circular coil of 1000 turns and average radius 10  is rotating about its horizontal diameter at . If the vertical component of earth's magnetic field at that place is  and electrical resistance of the coil is , then the maximum induced current in the coil will be:

The magnetic energy stored in an inductor of inductance  carrying a current of  is
