Use a magnetic field sensor to investigate the magnetic field strength of a permanent magnet as a function of distance from the magnet.
Although we cannot directly see the presence of magnetic fields, we can detect their existence. For example, we can use compasses positioned around the perimeter of a bar magnet. The needles in the compasses will align themselves with the magnetic field surrounding the magnet,
indicating the direction of the field lines. In this lesson, students investigate the strength of the magnetic field of a permanent magnet as a function of distance from the magnet.
Students gain experience conducting the following procedures:
Meter stick (non-metallic)
Neodymium magnet (1/2 or 3/4")
This experiment may require software and an interface for data collection.
