A 100-turn square wire coil of area 0.040 m2 rotates about a vertical axis at 1,450 rev/min, as indicated in the figure below. The horizontal component of Earth's magnetic field at the location of the loop is 2.0 ✕ 10−5 T. Calculate the maximum emf (in V) induced in the coil by Earth's field.

An emf is induced by rotating a 1060 turn, 20.0 cm diameter coil in the Earth's 4.85 x 10-5 T magnetic field. What average emf (in V) 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?

The straight wire that has been bent into a perfect circle has been placed in a perpendicular magnetic field has a length of 30.0 cm. The magnetic field is changing at a rate of 13 T/s. If the resistance of the wire loop is 3.6 Ω, the electric current in the wire will be:

A wire loop with an area of 1.4×10−2 m2 is in a magnetic field of 0.36 T directed at a angle 30 to the plane of the loop. If the field drops to zero in 36 msms , what is the average induced emf in the loop?

A square, 44.0-turn coil that is 13.0 cm on a side with a resistance of 0.900 2 is placed between the poles of a large electromagnet. The electromagnet produces a constant, uniform magnetic field of 0.400 T directed into the screen. As suggested by the figure, the field drops sharply to zero at the edges of the magnet. The coil moves to the right at a constant velocity of 3.10 cm/s. N-turn coil B into the screen V

A very large, superconducting solenoid such as one used in MRI scans, stores 1.00 MJ of energy in its magnetic field when 100 A flows. If the coils “go normal,” they gain resistance and start to dissipate thermal energy. What temperature increase is produced if all the stored energy goes into heating the 1000 kg magnet, given its average specific heat is 200 J/kg.oC ?
