Physicist wraps a long copper wire around toilet paper roll

Reference no: EM13672640

A physicist wraps a long copper wire around a toilet paper roll and places the roll in a uniform magnetic field. The axis of the roll is aligned by the field. The radius of the roll is r = 5 cm and the strength of the field is B = 0.1 T. If the physicist pulls the wire at v = 45 cm/s, what is the magnitude of the EMF induced in the wire?
