Introduction
When playing with a magnet, you have probably found that objects were more strongly attracted when they were closer to the magnet. In this experiment, you will first use a computer-interfaced Magnetic Field Sensor to study magnetic field strength at various distances from a bar magnet. In the second part of the experiment, you will measure and map the magnetic field at one-centimeter intervals along the bar magnet.
Objectives
In this experiment, you will
- Measure magnetic field strength.
- Graph and analyze data.
- Make conclusions about the relationship between magnetic field strength and distance.
- Measure and graph magnetic field strength at points along a bar magnet.
- Make conclusions about the magnetic field at various points on a bar magnet.
Sensors and Equipment
This experiment features the following sensors and equipment. Additional equipment may be required.
