When the speed at which a conductor is moved through a magnetic field is increased, the induced voltage

 [A]. increases [B]. decreases [C]. remains constant [D]. reaches zero

Explanation:

No answer description available for this question.

 Aravindhsvcoe said: (Aug 13, 2011) Due to magnetic field flux is produced, if flux increase means induced emf is increased. The flux is directly proportional to induced emf.

 Bk Samal said: (Sep 2, 2011) e=no of pole*flux*speed*no of armature conductor

 Satish Thatithuri said: (Dec 29, 2011) In a generator induced emf is proportional to speed hence if speed increses obviously emf increases.

 Ashraf said: (Apr 15, 2012) E propotional to Speed.

 Karthik said: (Aug 13, 2012) It can also be derived from the formula, e=B*L*V. where e is the induced emf in the conductor when the conductor moves perpendicular to the field. L is the length of the conductor. V is the velocity of conductor. And hence e is proportional to the speed of conductor.

 Nirlipta Das said: (Sep 27, 2012) Speed of conductor is directly proportional to induced voltage. So when magnetic field is increased induced voltage also increase.

 Nirlipta Das said: (Sep 27, 2012) Speed of conductor is directly proportional to induced voltage. So when magnetic field is increased induced voltage also increase.

 Gururaj S said: (May 5, 2013) When the speed of conductor increases, the flux interact to conductor also increases so that the induced emf is increases in the conductor.

 Sonam said: (Aug 2, 2013) When the speed of conductor moving in presence of magnetic field increases, the number of magnetic lines of force cut by it increases and hence the induced voltage increase.

 Shiva said: (Aug 4, 2013) According to ohm's law current and voltage are inversely proportional. So voltage decreases.

 Sureshkumar Nelluri said: (Mar 3, 2014) Speed is proportional to induced emf and inversely proportional to flux.

 Rajvir Dhiman said: (Mar 16, 2014) Let us consider the conductor which is moved in between the magnetic poles of the magnet. After some time we increase its moving speed in between the poles, then we will found that the conductor experiences more force in it. Because when we increase the speed of moving conductor then it experience more and more forces (emf).

 S.Babu said: (May 31, 2014) According to faraday's 2nd law of electromagnetic induction magnitude of induced emf in conductor directly proportional to rate of changes of flux linkages to conductor. So when speed of conductor is increased rate of change of flux linkages also changed.

 Pesce said: (Jun 13, 2015) We know that: eb = flux*Z*N*P/(60*A). Hence, eb directly proportional to the speed (N). So as speed increases induced voltage will increase.

 Soumyaranjan Pradhan said: (Aug 30, 2015) According to Faraday's 2nd law voltage will increase here.

 Navinsam said: (Sep 26, 2015) Emf = blv. V velocity. If velocity increase, emf also increase.

 Ramchandra Ladkat said: (Sep 1, 2016) When a voltage is an increase, magnetic flux is produced. So conductor is a move in the magnetic field.

 Swetha said: (Aug 6, 2018) @Karthik. Your explanation is exactly correct.

 Somasekhar said: (Nov 5, 2018) Induced emf E = Z*N*FLUX/60.P/A. So here induced voltage is directly proportional to speed n.

 Muhammed said: (Jul 7, 2020) Induced EMF is increased with the speed of rotor.
