Q1.. Explain Faraday's law of induction and Lenz's Laws. The magnetic flux passes perpendicular to the plane of the circuit and is directed into the paper. If the magnetic flux varies with respect to time as per the following relation: B = (2t³ +3t2 + 8t +5) mWb, what is the magnitude of the induced emf in the loop when t= 3 s? Find out the direction of current through the circuit. X X XX www
Which option most accurately defines Faraday's law? Any change in the electric field over a conductor will produce an magnetic field inside a conductor. The voltage generated in a coil is inversely proportional to the cross-sectional area of the coils loops. Any change in the magnetic field over a conductor will produce an electromotive force and electric current in the conductor. The voltage generated in a coil is inversely proportional to the number of electrons in the loop.
