Suppose you rotate a 1000 turn, 19 cm diameter coil in the Earth’s 5.00 × 10-5 T magnetic field. What is the peak emf generated in V, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 8.5 ms?

A 500-turn circular loop 15.0 cm in diameter is initially aligned so that its axis is parallel to the Earth's magnetic field. In 2.77 ms the coil is flipped so that its axis is perpendicular to the Earth's field. If a voltage of 0.166 V is induced in the coil, what is the value of the Earth's magnetic field?

An emf is induced by rotating a 1000 turn, 19 cm diameter coil in the Earth’s 5.00 × 10-5 T magnetic field. d = 19 cm What average emf (in volts) is induced, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 13 ms?  εave =?

A 10-turn generator coil with area 0.150 m2 rotates in a 1.25-T magnetic field. At what frequency should the coil rotate to produce a peak emf of 150 V?

Figure  shows a 100-turn coil of wire of radius 12 cm in a 0.15 T magnetic field. The coil is rotated 90° in 0.30 s, ending up parallel to the field. What is the average emf induced in the coil as it rotates?

A coil of wire with a radius of  3.2cm is rotated at 85 rpm in a 0.075T magnetic field. What is the maximum emf generated?

A 2.00×10-2 Ω square wire loop 40.0 cm on a side has its plane normal to a uniform magnetic field of magnitude B = 3.0 T. If you pull two opposite sides of the loop away from each other, the other two sides automatically draw toward each other, reducing the area enclosed by the loop.If the area is reduced to zero in a time of 0.30 s what is the average emf during this time interval?  What is the average current during this time interval?

A wind turbine generator contains a circular coil that is rotated fully through a 100-turn cycle. If the average emf over 10 seconds equals 153 V, with magnetic field strength of 4.00 T, what would be the radius of the coil in meters?

A single circular loop of wire of radius 0.25m is positioned in a uniform magnetic field of 0.25T  that points out of the page. What is the magnitude of the average EMF induced in the loop if it's orientation changes from being in the plane of the page to out of/into the page over a time period of 0.59seconds?

A circular loop in the plane of a paper lies in a 0.65 T magnetic field pointing into the paper. The loop's diameter changes from 21.5 cm to 6.8 cm in 0.52 s . What is the magnitude of the average induced emf?
