Question

A closed loop conductor that forms a circle with a radius of 2 m is located in a uniform but changing magnetic field. If the maximum emf induced in the loop is 9 V, what is the maximum rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?

Answer 1

solution To Radius of loop - R=2m R : Area ea of loop, A: TR2 = 3./47(214 19.56 m2 A cs wow B perpendicader Now, suppose magnetic field is to place of loop shown, induetion Ace to Faraday's law of Electromagnetic Emf induced E = AO At 0 = if B and magnetic is perpendicular to plane of coop :. Q = AB, A flux, BA :. {= AB. A U AB at st Now, Masih Emt, &max=9v Emax= A AB At may = Erman = 0.717. OR / AB At max ro A 12.56
