Question # 1
A rectangular coil of area 0.5 m2 and 400 turns is rotating with angular velocity of 3 rad.s−1 in a magnetic field of 0.2 T. Calculate the maximum value of induced emf in the coil.
Question # 2
The maximum value of alternating current induced in an AC generator is 15 A. Calculate the value of current at the instant of 0.4 s. The rotational speed of the generator is 20 rad.s−1.
Question # 3
How will you represent the direction of a magnetic field that is directed away from you i.e. into the paper?
Question # 4
A rectangular coil of area 0.5 m2 and 500 turns is rotating with angular velocity of 2 rad.s−1 in a magnetic field of 0.2 T. Calculate the induced emf in the coil at the instant when angle between field and normal to the plane is 60°.
Question # 5
The maximum value of induced emf of generator is 250 V. If the resistance of the coil of generator is 50 Ω, then calculate the maximum value of induced current.
