Motors / Generators

Learn about motors and generators! Discover how they convert energy and relate electricity to magnetism.

#1) What are the two major parts of a motor / generator? Two electrodes Nail and battery Coil of copper wire and permanent magnet One temporary magnet and one permanent magnet #2) Sort the information into "Motor" or "Generator." Motor The energy transfer is generally electrical to mechanical. Makes movement Blender Car engine Ceiling fan Shows how an electric current can produce a magnetic field. Generator The energy transfer is generally mechanical to electrical. Makes electricity Windmill Solar panel Hydroelectric dam Shows how a magnetic field can produce an electric current. #3) In this picture, is the propeller on a motor or a generator?**The propeller is spinning on its own.** Motor Generator #4) In this picture, is the propeller on a motor or a generator?**The propeller is being spun.** Motor Generator #5) Which of the following best summarizes the relationship between a motor and a generator? Motors and generators are made of different materials but have the same function. Motors and generators are made of different materials and have opposite functions. Motors and generators are made of the same materials but have opposite functions. Motors and generators have no relationship. #6) Which of the following best summarizes the relationship between electricity and magnetism? Magnets and electric currents must remain separate at all times. An electric current can produce a magnetic field and a magnetic field can produce an electric current. A magnetic field can produce an electric current but an electric current cannot produce a magnetic field. There is no relationship between electricity and magnetism. #7.) A magnet is being pushed through a coil of wire. What will happen? Radiant energy will be produced. The magnetic field will become stronger. Electrical energy will flow through the wire. Nothing will happen.
