Generators use a magnetic field of which of the following to produce an electric current?

I need help with 2 basic quetions?

Quote In the simplest terms, a motor works by current moving through a magnetic field, creating mechanical movement (spinning a rotor).Quote
Can some one explain this better.
Quote A dynamo works in reverse – mechanical movement spins a magnetic field, creating current. Quote
sorry I do not know how a dynamo works or how a [...]

what is the max emf output? what would be the max emf output if 10 such loops were used instead?

a student makes a simple generator by using a single sq. loop 10 cm on each side. the loop is then rotated at a frequency of 60Hz in a magnetic field of 0.015T.

moving on to light speed?

a guy I know who is working for boeing, and he has told me alot of interesting things about what they are doing to move us forward in space travel. He said that they are working on a device that reduces the actual weight of objects by produceing a unusual magnetic field . he said [...]

which of the following statements is false?

a. an electric current is generated in a wire when the wire is moved so that it cuts across field lines
b. current can be made to flow in a stationary wire by a moving a magnetic field parallel to the wire
c. the electromotive force depend only on the magnetic field strength, the length of the [...]
