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 coil has an area of 100 cm? with 198 turns connected across a 5.00 Q resistor to form a closed circuit as in the figure. Initially, a 1.2 T uniform magnetic field points upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.2 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.100 s, what is the average current (in units of A) in the coil during that time? Select one: OA. 13.07 ОВ. 10.69 OC.4.75 OD. 9.50 OE 2.38

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 =?

An elastic conducting material is stretched into a circular pop of 15.9 cm radius. It is placed with its plane perpendicular to a uniform 0.646 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 89.2 cm/s. What emf is induced in volts in the loop at that instant? Number: Units V

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?

An emf is induced by rotating a 1000-turn, 20.0 cm diameter coil in the Earth's 5.00 x 10-5T magnetic field. What average emf 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 10.0 ms?

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?
