There is a magnetic field B perpendicular to the rails (out of the page), and a conducting bar can slide over the rails perpendicular to them as well as the field, as shown in the diagram below (Note, assume that any field effects from the battery are negligible.) The bar is placed on the rails, starts from rest, and accelerates conducting bar left down conducting friction less rails Consider the situation as described and select True or False for each of the following statements | True The direction of the induced e.m.f in the bar will be up | True | The bar will accelerate away from the battery True Faraday's Law is such that changing magnetic fields generate electric fields False If the magnetic field were reversed, the bar would accelerate towards the battery False :| Lenz's Law is such that induced currents produce magnetic fields that tend to oppose the flux changes that induce those currents Submit AnswerIncorrect. Tries 4/10 Previous TriesExplanation / Answer
(a) True
Explanation : Direction is in such that it opposes the emf which produeces it.
(b)False
Explanation: It accelerates towards the battery.
(c)False
Explnation : changing magnetic field generates emf.
(d)False
Explanation : It will move away from battery.
(e)True
Explanation:According to Lenzs Law the produced emf is such that it opposes the changes that produes it.
