Electro Magnetic Induction And Alternating Currents Question 452

Question: A conductor AB of length $ l $ moves in x - y plane with velocity $ \vec{v}=v_{0}(\hat{i}-\hat{j}) $ . A magnetic field $ \overset{\to }{\mathop{B}}=B_{0}(\hat{i}+\hat{j}) $ exists in the region. The iduced Emf is

Options:

A) zero

B) $ B_{0}lv_{0} $

C) $ B_{0}lv_{0} $

D) $ \sqrt{2}B_{0}1v_{0} $

Show Answer

Answer:

Correct Answer: A

Solution:

  • $ \vec{\ell },\vec{v} $ , and $ \vec{B} $ are coplanar.
