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.


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.
