SATHEE: Electro Magnetic Induction And Alternating Currents Question 369

Electro Magnetic Induction And Alternating Currents Question 369

Question: A 50 turns circular coil has a radius of $3 c m$ , it is kept in a magnetic field acting normal to the area of the coil. The magnetic field $B$ increased from 0.10 tesla to 0.35 tesla in 2 milliseconds. The average induced e.m.f. in the coil is [MP PET 1994]

Options:

A) $1.77 v o l t s$

B) $17.7 v o l t s$

C) $177 v o l t s$

D) $0.177 v o l t s$

Show Answer

Answer:

Correct Answer: B

Solution:

$e = - \frac{N (B_{2} - B_{1}) A \cos θ}{Δ t}$ $= - \frac{50 (0.35 - 0.10) \times π {(3 \times 10^{- 2})}^{2} \times \cos 0^{o}}{2 \times 10^{- 3}}$ $, = 17.7 V$ .
