Electro Magnetic Induction And Alternating Currents Question 483
Question: A cylindrical region of radius 1 m has instantaneous homogenous magnetic field of 5T and it is increasing at a rate of 2T/s. A regular hexagonal loop ABCDEFA of side 1 m is being drawn in to the region with a constant speed of 1 m/s as . What is the magnitude of emf developed in the loop just after the shown instant when the corner A of the hexagon is coinciding with the centre of the circle?
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
-
The induced emf across the ends B and F due to motion of the loop,
The induced emf across the loop due to change in magnetic field
