An elastic conducting material is stretched into a circular loop of 12.6 cm radius. It is placed with its plane perpendicular to a uniform 1.17 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 57.9 cm/s. What emf is induced in volts in the loop at that instant? Number i Units

A 34-turn circular coil of wire has diameter 0.92 m. It is placed with its axis along the direction of the Earth's magnetic field of 41.0 µT and then in 0.200 s is flipped 180°. An average emf of what magnitude is generated in the coil?

The figure below shows a flexible loop of metal wire with a radius of 15.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.130 T. An engineer grabs the loop at points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.220 s. A В What is the average induced emf (in mV) in the loop over this time span? mV

A 13.0 m long, thin, uniform steel beam slides north at a speed of 20.0 m/s. The length of the beam maintains an east-west orientation while sliding. The vertical component of the Earth's magnetic field at this location has a magnitude of 48.0 µT. What is the magnitude of the induced emf between the ends of the beam (in mV)? mV What If? The west end of the beam impacts and sticks to a pylon, causing the beam to rotate counterclockwise as viewed from above. While the beam rotates, what is the magnitude of the induced emf between the ends of the beam (in mV)? (Hint: use conservation of angular momentum to find the speed of the beam after the collision.) mV

A 32-turn circular coil of wire has diameter 0.91 m. It is placed with its axis along the direction of the Earth's magnetic field of 42.0 µT and then in 0.200 s is flipped 180°. An average emf of what magnitude is generated in the coil?

Two moving rods of equal lengths (1.20 m) are moving as shown in the figure. The speed v1 = 1.10 m/s and the speed v2 = 2.00 m/s. If the magnetic field is uniform with a magnitude of 0.60 T, what is the magnitude of the average emf in the loop?

A square, single-turn coil 0.27 m on a side is placed with its plane perpendicular to a constant magnetic field. An EMF of 19 mV is induced in the winding when the area of the coil decreases at a rate of 0.11 m2/s. What is the magnitude of the magnetic field?
