A horizontal wire 24 cm long falls in the field of flux density 0.8 T. Calculate the emf induced in it at the end of 3s, after it was dropped from rest. Suppose the wire moves perpendicular to its length as well as to magnetic field. Take `g=9.8 ms^(-2)`

A wire is moving with velocity 12xx10^(-2) m/s in a magnetic field of 0.5 T. if the induced emf is 9 mV, the length of wire is

A horizontal wire 0.8 m long is falling at a speed of 5 m//s perpendicular to a uniform magnetic field of 1.1 T , which is directed from east to west. Calculate the magnitude of the induced ernf. Is the north or south end of the wire positive?
