Electro Magnetic Induction And Alternating Currents Question 376
Question: A coil of 100 turns and area 5 square centimetre is placed in a magnetic field B = 0.2 T. The normal to the plane of the coil makes an angle of 60° with the direction of the magnetic field. The magnetic flux linked with the coil is [MP PMT 1997]
Options:
A) $ 5\times {{10}^{-3}}Wb $
B) $ 5\times {{10}^{-5}},Wb $
C) $ {{10}^{-2}},Wb $
D) $ {{10}^{-4}},Wb $
Show Answer
Answer:
Correct Answer: A
Solution:
$ \varphi =NBA\cos \theta =100\times 0.2\times 5\times {{10}^{-4}}\cos 60^{o} $ $ =5\times {{10}^{-3}}Wb $
