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 $
