Riehting the induced emf

The principle of the generator
A looped conductor is bent in a magnetic field between the two magnetic poles N and Z. The field direction is indicated by pijitjes. We move the conductor in the magnetic field in the direction of pijien, then it is an induced emf of induction. The direction of the induced emf, we can determine the rights terhandregel
Keep one thumb, forefinger and middle finger of the right way, d ^ t they are perpendicular to each other, with the index finger toward the field, and the thumb indicates the direction of motion, then the middle finger points toward the induced emf on. The chain is closed, then the rule also applies to the direction of flow.
Using this rule, we note that in Figure 44 in the guide along the north pole moves, the emf is opposite to that along the South Pole. By the conductors on one side connecting the two emf in series.
We are now a connection between the conductors and a power load (lamp), then formed a circle and it creates a current that makes the lamp glow. Pijien in the windings indicate the flow direction.
The flow takes place only when an emf is gei'nduceerd and this is only the case if we move the conductor, perpendicular to the direction of the force.
Pig. 46 aj show an anchor, which is only one winding is placed in order of the letters, each one is rotated 45 °. One determines for each of the positions drawn toward the emf, it appears that in this thread I for the positions b, c and d facing forward, in wire II in that positions the direction of the emf to the rear. In positions a, e and j is no emf gei'nduceerd both threads, because no lines are cut.
Searching the direction of the emf in the wire I for positions f to h, then we noticed that she was to the rear. In lead II during this half revolution the emf forward. It follows that a veil during the revolution emf in the leads has been a change of direction and also that increasing the emf in each winding support, as they are switched in series ¬ oped. This wisselinq apparently takes place when the coil positions a, e and j passes, the state,
