Electro Magnetic Induction And Alternating Currents Question 437

Question: The magnetic induction in the region between the pole faces of an electromagnet is 0.7 weber/m2. The induced e.m.f. in a straight conductor 10 cm long, perpendicular to B and moving perpendicular both to magnetic induction and its own length with a velocity 2 m/sec is [AMU (Med.) 1999]

Options:

A) 0.08 V

B) 0.14 V

C) 0.35 V

D) 0.07 V

Show Answer

Answer:

Correct Answer: B

Solution:

$ e=Bvl\Rightarrow e=0.7\times 2\times (10\times {{10}^{-2}})=0.14\ V $
