Flemings right hand rule:
When a straight wire is moved through a magnetic field, an emf is induced in it, in the manner of the coil and magnet experiment. Once again, lines of flux are being cut by a conductor and if the wire forms part of a closed circuit, a current will flow. The same effect is observed if the wire is stationary and the magnetic field moves. The direction of the induced emf may be determined by Fleming's Right Hand Rule.
The thumb, first finger and second finger of the right hand are held at right angles to each other, then:
• With the thuMb pointing in the direction of the conductor movement.• With the First finger pointing in the direction of the magnetic field (N to S).• Then the seCond finger points in the direction of conventional current flow and thus indicates the direction of the induced voltage.
Work: In its technical sense, work is the product of force and distance, and work is done only when a force causes movement. We can see this by the formula: Work = Force x
