A circular conducting loop of 5 turns and 0.040 m in radius is perpendicular to a magnetic field of 0.250 T (directed into the page as shown).  The loop is stretched across the diameter, so that its area goes to zero in 0.10 s.  Determine the magnitude of the average induced EMF.

A circular conducting loop with radius 2.80 cm is placed in a uniform magnetic field of 0.650 T with the plane of the coil perpendicular to the magnetic field as shown. Axis The magnetic field decreases to 0.190 T in a time interval of 28.0 ms. What is the average induced emf in the loop during this interval?

A prototype of an MRI consists of a set of 600 coils each having a radius of 0.20 m. To test its efficiency a 1.8 T magnetic field oriented perpendicular to the plane of the coils is shut off over a 3.2 second time interval. What is the induced current in the coils? The resistance is 15ohms

Induced EMF Below is a closed conducting loop within a magnetic field (for direction see picture). The loop is a circle with a radius of r = 5.00 cm. The magnetic field is decreasing in the direction shown at a rate of dB/dt = 157.0 mT/s. The circle wire has 305.0 loops around it. The wire has a total resistance of R = 2.80 Ohms. Magnetic Field (into the page) 8) What is the induced current around the wire in this system?

A 42 turn conductive loop encloses an area of 0.68 m2. At what constant rate should the magnetic field directed perpendicular to the loop change with time if the induced emf is to be 3.6 Volts? Consider only positive numbers here in your answer.

A 36 turn conductive loop encloses an area of 0.69 m2. At what constant rate should the magnetic field directed perpendicular to the loop change with time if the induced emf is to be 4.12 Volts? Consider only positive numbers here in your answer.

A circular loop is hanging on the wall. It has a radius of 33.3 cm and is comprised of ) 12 coils. There is a magnetic field perpendicular to the wall, coming out of the wall, that grows from 1.5 T to 7.5 T in 3.0 seconds. The coil has a resistance of 3.752, what is the magnitude and direction of the induced current in the coil?
