hen a conducting loop of resistance 10 Ω and area 10 cm2 is removed from an external magnetic field acting normally, the variation of induced current in the loop with time is shown in the figure.

A conducting loop of radius 10π√cm is placed perpendicular to a uniform magnetic field of 0.5T. The magnetic field is decreased to zero in 0.5s at a steady rate. The induced emf in the circular loop at 0.25s is:

A loop of area 10 cm2 is placed in a uniform magnetic field of 0.5 T with its plane perpendicular to the field. the resistance of the loop is 5 Ω. The loop is suddenly removed from the field. The total charge flown through the loop is 10–x C. Find x.

A square loop of side 10 cm and resistance 0.7Ω is placed vertically in east-west plane. A uniform magnetic field of 0.20 T is set up across the plane in north east direction. The magnetic field is decreased to zero in 1 s at a steady rate. Then, magnitude of induced emf is x√×10−3 V. The value of x is _____

The loop in the image is moving through the magnetic field, of strength 0.700 T, at a speed of 27.0 m/s. If the resistance in the loop is 1.10 Ω and the width of the wire is x = 9.00 cm, what is the magnitude and direction of the induced current?
