Say for you had a wire in a complete circuit inside a magnetic field (pointing inwards) perpendicular to the wire.
You move the wire across (to the right) , cutting lines of flux, this induces a current in the wire.
The induced current acts upwards using the dynamo rule (thumb is motion, middle finger is flow of electrons, first finger is field)
But since an induced current is created upwards in a magnetic field this means that a force is also created.
Using Fleming's left hand rule (thumb is motion, middle finger is conventional current and first finger is field), the motion of the wire is to the right.
More lines of flux are then cut, current increases, speed increases ect you get energy out of nothing?
How is this possible?
