A circular coil has 
, radius 
and resistance 
. The coil is co-axial with a solenoid of 200 turns 
and diameter 
. If the solenoid current is decreased from 
to zero in 
, then the current induced in the coil is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
No. of turns in circular coil, 
Radius, 
Resistance, 
No. of turns per unit length in the solenoid, 
∵ Magnetic field inside the solenoid, 
Hence, induced emf
Induced current,
