A long solenoid has turns per cm. A small loop of area is placed inside the solenoid normal to its axis. If the current carried by the solenoid changes steadily from to in , what is the magnitude of the induced emf in the loop while the current is changing?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Magnetic field due to solenoid along its axis, B=μ0nI=4π×10-720×102I=8π×10-4I T Now induced EMF due to change in magnetic flux can be written as,…
