Faraday’s Law Introduction:
Michael Faraday was an English scientist that greatly contributed to the study of electromagnetism including building one of the first electric motors. He also contributed to how induction occurs. In this simulation, we will be experimenting with the process of induction.
1. What happens as you move the north side of the magnet into the coil?
2. How does the Voltage change as you move the south side in rather than the North?
3. What happens if you move the magnet into the coil very slowly vs. very quickly. What relationship can you make between the motion of the magnet and the current produced?
4. Can you produce a current when the magnet goes up and down in the loops? Explain why and make sure you use "field lines" in your answer.
5. Next try two rings vs. four rings. What relationship can you make between the number of loops and the current produced.
6. Lastly, try putting the magnet in the loops and click the magnet flip button. What happens as you spin the magnet several times?
7. Look at the Voltage needle as you spin it multiple times. What type of current do you think it is producing? AC or DC?
8. Conclusion: Write 3-5 sentences on what you learned from this activity.

Clothes dryer uses about 7 amps of current from a 240 volt line. how much power does it use?

Aheat engine running backward is called a refrigerator if its purpose is to extract heat from a cold reservoir. the same engine running backward is called a heat pump if its purpose is to exhaust warm air into the hot reservoir. heat pumps are widely used for home heating. you can think of a heat pump as a refrigerator that is cooling the already cold outdoors and, with its exhaust heat qh, warming the indoors. perhaps this seems a little silly, but consider the following. electricity can be directly used to heat a home by passing an electric current through a heating coil. this is a direct, 100% conversion of work to heat. that is, 19.0 \rm kw of electric power (generated by doing work at the rate 19.0 kj/s at the power plant) produces heat energy inside the home at a rate of 19.0 kj/s. suppose that the neighbor's home has a heat pump with a coefficient of performance of 4.00, a realistic value. note: with a refrigerator, "what you get" is heat removed. but with a heat pump, "what you get" is heat delivered. so the coefficient of performance of a heat pump is k=qh/win. an average price for electricity is about 40 mj per dollar. a furnace or heat pump will run typically 200 hours per month during the winter. what does one month's heating cost in the home with a 16.0 kw electric heater? what does one month's heating cost in the home of a neighbor who uses a heat pump to provide the same amount of heating?
