What are the factors in determining the amount of emf generated.
- density of the magnetic flux
- length of conductor within the magnetic field
- rate at which the conductor cuts the lines of
magnetic force (the rate of cutting is
determined by the speed of the conductor and the angle it is at)
When does a conductor generates maximum emf?
When it cuts directly across the (magnetic) lines of force. At an angle of 90° and 270°.
When is no emf generated?
When it is moving parallel to the (magnetic) lines of force. At an angle of 0° and 180°.
When does an electromotive force (emf) or voltage develop in a conductor.
Where there is relative motion between the conductor and magnetic flux.
At what rate does a conductor cut the lines of force in a magnetic field, if it travels at a constant speed on a circular path around a center
point?
At a constantly changing rate.
