- Students will describe the magnetic field around an electromagnet.
- Students will relate the strength of a solenoid-type electromagnet to the number of turns of a wire on the electromagnet.

About the Lesson
In this lesson, students will create a solenoid-type electromagnet using two different methods of coiling the wire around the core. They will use a sensor to determine the relationship between the number of turns of wire and the magnetic field strength for each method.
