in motors, when a current is supplied to the circuit, the directon of the force can be deteremined using right hand palm rule.

the back emf produced opposes the original current, so the direction of the back emf is just simply reverse?

in gnerators, when electricity is being generated, is the direction same as the motor, or is it the same as back emff?
but if it is the same as the direction of the back emf, ...then,,,,isn't it produced on the same theory of the way which back emf was produced?

btw, when they say emf are they referring to current or voltage?

yes on a generator its the same principle as the back emf
its cos the coil is going to produce a current to oppose the change in magnetic flux
