What is the difference between the motor effect and the dynamo effect?

I'm really struggling, can anybody define them both for me and tell me how they work?

motor effect: when a force is made due to a wire carrying a current cutting through a magnetic field.
dynamo effect: when a force is made due to moving the magnet - so the magnetic field moves so the wire cuts through it.

they are the same but with motor effect you move the wire, with dynamo effect you move the magnet.
hope it helped, good luck in the exam!

motor effect: electrical energy -> kinetic energy. uses the Fleming's left hand rule. about electromagnetism.

dynamo effect: kinetic energy -> electrical energy. uses the Fleming's right hand rule. about electromagnetic induction.
