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. Background information

The strength of an electromagnet depends on several factors, including the number of coils wrapped around the coil 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 the electromagnet by wrapping copper wire around a nail. For one of the 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 used their electromagnets to see how many paperclips each can pick up.

Data

For each electromagnet, two trials were conducted at each voltage. The data was recorded in the tables below.
