Electromagnet Strength Investigation Link for simulation: https://phet.colorado.edu/en/simulations/magnets-and-electromagnets Set up your window to the "Electromagnet" simulation Make sure your "Show Field Meter" and "Show Field" are both selected, and you are using a DC power source. Part 1: Pre-Lab Knowledge 1. Draw the circuit diagram for a single-cell battery connected with a coil of wire. Label the positive and negative ends of the battery, and draw the direction and poles of the coil's magnetic field.Part 2: Modifying Parameters Fill in the table below with your measurements for magnetic field strength (in Gauss) based on the parameters outlined in the first column. Electromagnet How Many Paperclips Did It Pick Up? +10 V, 4 coils +10 V, 2 coils 5 V, 4 coils 5 V, 2 coils -10 V, 4 coils -10 V, 2 coils 9. How does changing the number of coils affects the magnetic field strength? What is the mathematical relationship? 10. How does changing the voltage of the battery affect the magnetic field strength? What is the mathematical relationship?2. Reverse the voltage of the battery. Draw the battery, coil and magnetic field as you did in #1. Label the positive and negative ends of the battery, as well as the direction and poles of the coil's magnetic field. 3. Turn off the voltage in the battery. What happens to the magnetic field? What rule can explain this
