Learning to Use a Magnetic Field Sensor

Experiment #1 from Investigating Magnetism

Education Level
Elementary School


Have you ever played with magnets? One reason why they are fun and interesting is that they can have an effect on objects around them. This is because magnets are surrounded by a magnetic field. You may have seen the ends of magnets labeled as a north pole or south pole, just like the Earth. The Magnetic Field Sensor will help you find the north and south poles of a magnet.


  • Learn how to use a Magnetic Field Sensor.
  • Measure the magnetic field of a bar magnet.
  • Identify the north and south poles of a bar magnet.
