In this assignment, you will review some student lab results on electromagnets. You will analyze the data and graph the results. You will then present your results on the Student Worksheet found at the end of this document.
_
The strength of an electromagnet depends on several factors, including the number of coils wrapped around the core of the electromagnet and the voltage of the power source. The greater the number of coils, the stronger the electromagnet. And, the greater the voltage, the stronger the electromagnet.
_
A group of students has been testing electromagnets in the lab. They made an electromagnet by wrapping copper wire around a nail. For one set of tests, they wrapped the wire around the nail 25 times. For the second set of tests, they wrapped the wire around the nail 50 times. They also have 4 different batteries: 1.5 V, 3.0 V, 4.5 V, and 6.0 V. They use their electromagnets to see how many paper clips each can pick up.
_
Make a line graph of the data found above. On the same graph, show the average number of paper clips each electromagnet picked up for each voltage tested. Plot the voltage on the x-axis and the average number of paper clips picked up on the y-axis. Scale the x-axis in intervals of 1.5 volts and scale the y-axis in intervals of 5 paper clips.
_
Look at the data table and graph for the 25-coil electromagnet. With the 1.5 V battery, the electromagnet picked up an average of 6 paper clips, and with the 6.0 V battery, it picked up an average of 23 paper clips.
