Electromagnets: Winding Things Up
Experiment #26 from Physical Science with Vernier
- Subject
- Physical Science
Introduction
A magnetic field forms around a wire that has an electric current in it. Winding a wire around a piece of iron increases the strength of the magnetic field. A temporary magnet made in this way is called an electromagnet. In this experiment, you will use a computer-interfaced Magnetic Field Sensor to study the relationship between number of wire winds and magnetic field strength of an electromagnet.
Objectives
In this experiment, you will
- Build an electromagnet.
- Measure magnetic field strength.
- Graph the results.
- Make conclusions about the relationship between number of wire winds and magnetic field strength.
