The direction of induced emf can be find out by the ‘Fleming’s right hand rule’, and ‘lenz’s law’
Fleming’s right-hand rule:Fleming’s right hand rule states that, if one extends the thumb, fore finger and middle finger of the right hand at right angle to each other in such a way that the thumb point in direction of motion of the conductor, the fore finger in the direction of flux (from north to south pole), then the middle finger is indicate the direction of the induced emf in the conductor.
Lenz’s law:The lenz’s law states that, electro magnetically induced current always flows in such a way or direction that the action of magnetic field set up by induced current tends to opposes the root cause which produces it.
