Electro Magnetic Induction And Alternating Currents Question 462
Question: A rectangular coil has a long straight wire passing through its centroid perpendicular to its plane as shown. If current through the wire varies as $ i=i_{0}\sin \omega t $ , induced current in the coil will be (Given R = Resistance of the coil)
Options:
A) $ \frac{i_{0}\sin \omega t}{R} $
B) $ \frac{\pi a\sin \omega t}{bR} $
C) zero
D) $ \frac{\pi a\cos \omega t}{bR} $
Show Answer
Answer:
Correct Answer: C
Solution:
- The magnetic flux through the coil will be zero, and so induced emf in it will be zero.
