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.
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.
