A 2.80-m length of wire is held in an east-west direction and moves horizontally to the north with a speed of 0.250 m/s. The Earth's magnetic field in this region is of magnitude 50.0 µT and is directed northward and 53.0° below the horizontal.
(a) Calculate the magnitude of the induced emf between the ends of the wire.
(b) Determine which end is positive.
- the east end
- the west end
- both
- neither
