\n2. The phenomenon<\/strong> of generation of current or emf by changing the magnetic flux is known as Electromagnetic Induction EMI).
\n3. Faraday\u2019s Law of Electromagnetic Induction<\/strong>
\nFirst Law<\/strong> Whenever magnetic flux linked with the closed loop or circuit changes, an emf induces in the loop or circuit which lasts so long as change in flux continuous.
\nSecond Law<\/strong> The induced emf in a closed loop or circuit is directly proportional to the rate of change of magnetic flux linked with the closed loop or circuit
\n
\nwhere, N = number of turns in loop.
\nNegative sign indicates the Lenz\u2019s law.
\n4. Lenz\u2019s Law<\/strong> The direction of induced emf or induced current is such that it always opposes the cause that produce it.<\/p>\n
\n5.<\/strong> If N is the number of turns and R is the resistance of a coil. The magnetic flux linked with its each turn changes by d\u0424 in short time interval dt, then induced current flowing through the coil is
\n
\n6. If induced current<\/strong> is produced in a coil rotated in a uniform magnetic field, then
\n
\n7. Motional Emf<\/strong> The potential difference induced in a conductor of length l moving with velocity v, in a direction perpendicular to magnetic field B is given by
\n<\/p>\n
\n
\n9. The induced emf<\/strong> developed between two ends of conductor of length l rotating about one end with angular velocity \u03c9 in a direction perpendicular to magnetic field is given by,

\n(i) putting the coil\/loop\/circuit in varying magnetic field.
\n(ii) changing the area A of the coil inside the magnetic field,
\n(iii) changing the angle 0 between B and A.<\/p>\nCBSE Notes<\/a><\/h4>\n","protected":false},"excerpt":{"rendered":"
