FACTORS AFFECTING INDUCED EMF

By experiment, the following factors may be noted:
• The faster the magnet (or coil) is moved, the greater is the deflection obtained on the meter. This shows that the magnitude of the emf is proportional to the rate of relative movement.
• Repeating the experiment using a stronger magnet results in greater meter deflection for the same rates of movement. Hence the magnitude of the emf is proportional to the flux density.
• Reversal of the direction of motion produces meter deflecting in the opposite sense. The direction of the induced emf therefore depends on the direction of motion.
• Using the south pole of the magnet instead of the north results in meter deflections in the opposite sense, showing that the direction of the induced emf depends upon the direction of the magnetic field.
• If more turns are used on the coil, meter deflection is greater and is proportional to the number of turns (N).
