# Two students hold a long wire and rotate it across the earth’s

Two students hold a long wire and rotate it
across the earth’s magnetic field so that the wire traces a circular path of
radius 1.2 m. The motional emf produced
in the rope is then measured on a voltmeter. If the angular frequency of
rotation is w = 12 rad.s-1, calculate the maximum possible motional emf in the
wire. (Use B = 0.3 G = 0.3Ã10-4 T for the Earthâs magnetic field.)
