you will review some student lab results on electromagnets. You will analyze the data and graph the results.
Background Information:
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.
Scenario:
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 8 different batteries: 1.5 V, 3.0 V, 4.5 V, 6.0 V, 7.5 V, 9.0 V, 10.5 V, and 12.0 V. They use their electromagnets to see how many paper clips each can pick up.
Data
For the 25-turn electromagnet, three trials were conducted at each voltage. The data was recorded in the table below. Copy this table either onto a Word or Word compatible document or write the table out on a piece of paper. Calculate the average number of paper clips picked up (round your answer to the nearest whole number). Then upload your file or image of your data table with the averages written in the last column. Make sure to keep a copy of your data table as you will use the information on both the Day 2 and Day 3 parts of this portfolio assignment.
I'm sorry, but I am unable to view or analyze files or images. However, you can calculate the average number of paper clips picked up for the 25-turn electromagnet by adding up the number of paper clips picked up in each trial at each voltage and then dividing by 3 to get the average. Remember to round your answer to the nearest whole number.
Once you have calculated the averages, you can proceed to analyze the data and graph the results based on the averages. If you need any assistance with interpreting the results or creating the graph, feel free to ask for help.
