Electromagnets
Recommended for grades K–5.
Introduction
Have you ever made a magnet with a nail, some wire, and a battery? This kind of magnet is called an electromagnet because it uses an electric current traveling through a wire to make the magnet. To make the electromagnet in this activity, a wire will be wrapped around the nail and then the wire will be connected to the ends of the battery.
Objectives
In this activity, you will
- Make an electromagnet using a steel nail, wire and a D battery.
- Measure the strength of the magnet as you wrap more wire around the nail.
Sensors and Equipment
This experiment requires each of the following Vernier sensors and equipment (unless otherwise noted):
Additional Requirements
You may also need an interface and software for data collection. What do I need for data collection?
