Question 1
A square coil ACDE with its plane vertical is released from rest in a horizontal uniform magnetic field 
of length 2L. The acceleration of the coil is-
of length 2L. The acceleration of the coil is- Question 2
A circular coil is placed in a uniform magnetic field such that its plane is perpendicular to the field. The radius of the coil changes with time as shown in the figure. Then which of the following graph represent the induced emf in the coil with time –
Question 3
A circular loop of wire of radius r rotates about z-axis with angular velocity ω. The normal to the loop is always perpendicular to z axis. At t =0 , normal parallel to y axis. An external magnetic field
= By
+ Bz
is applied. The EMF induced in the loop at time 't' -
= By + Bz is applied. The EMF induced in the loop at time 't' - Question 4
A metallic ring is held horizontal and a magnet is allowed to fall vertically through it with N-pole pointing upwards. The acceleration of magnet near the ring is a. Then-
Question 5
Two identical coaxial circular loops carry a current i each circulating in the same direction. If the loops approach each other-
Question 6
Figure shows a uniform magnetic field B confined to a cylindrical volume and is increasing at a constant rate. The instantaneous acceleration experienced by an electron placed at P is –
Question 7
5.5 × 10–4 magnetic flux lines are passing through a coil of resistance 10 ohm and number of turns 1000. If the number of flux lines reduces to 5 × 10–5 in 0.1 sec. The electromotive force and the current induced in the coil will be respectively-
Question 8
Two coils A and B have coefficient of mutual inductance M = 2H. The magnetic flux passing through coil A change by 4 Weber in 10 seconds due to the change in current in B. Then-
