Begin on the "Bar Magnet" tab. What can you change about the simulation? 2) What happens to the compass as you move it around the magnet? Insert a picture of what you see below 3) What do you notice about the arrows the further they are from the magnet? What do you think this means?Part 2 - Pickup Coil 4) Find two ways to make the light bulb light up. Describe them in the table below. Method Picture Description8 5) Select one of your methods and now try to increase the brightness of the bulb by changing the properties of the pickup coil. Item How it influences the brightness of the bulb 6) Why do you think it is called a pickup coil? Part 3 - Generator 6) Using what you have learned with the pickup coil, you will now design the best generator ever (that the sim will allow!). Make a list of the characteristics you think it should have below. 7) Test your ideas out using the simulation. How does the simulation accomplish what you wanted it to? Does it include anything additional?View Insert Format Tools Extensions Help Accessibility kami 100% - Normal text - Calibri 12 B IUA LLY 8) We have seen that a changing magnetic field will "induce" an electric current in a wire. What is another word for "induce" in this sentence? Part 4 - Right Hand Rule 9) Use X's and O's to show where the magnetic field will go into the page (X) an come out of the page (O) for the following current carrying wires. (Double click on the images to take you to google draw and use the shapes icon to insert your magnetic field)100% Normal text Calibri 12 8 10) Suppose the wire pictured in problem 9 carries a current of 12 Amps. If we were to measure the strength of the magnetic field at a point .005 m from the wire, what would the magnitude and direction of the magnetic field be? Part 5 - Big Ideas 11) It is sometimes said that a motor is the opposite of a generator. Why is this true? 12) Why does the magnet inside of a turbine need to be spinning in order to produce electricity? 13) What happens to the direction of current induced in a wire as the magnet inside of a turbine spins
