Determine the magnitude of the horizontal component

Reference no: EM13676902

A 0.80 meter Aluminum bar is held with its length parallel to the east-west direction and dropped from a bridge. Just before the bar hits the river below, its speed is 22 meter per second, and the emf induced across its length is 6.5E-4 Volt. Assuming the horizontal component of the earth's magnetic field at the location of the bar points directly north,

A) Find the magnitude of the horizontal component of the earth's magnetic field?

B) State whether the east end or the west end of the bar is positive.
