Induced E.M.F in a Straight Conductor

The induced e.m.f is produced in a straight conductor when the conductor moves along the lines of force of a uniform magnetic field

The direction of the e.m.f is given by Fleming’s right-hand rule which states that:

When the first three fingers of the right hand are held at right angles to each other, the forefinger points in the direction of the magnetic field, the thumb in the direction of the conductor, and the second finger points in the direction of the induced current, I, or induced e.m.f.

The induced current or e.m.f is maximum when the conductor is at right angles to the lines of the magnetic field and to conductor length.
