Induced voltage pulse and Faraday’s law of induction with Cobra4 Xpert-Link

A permanent magnet drops through a coil with different velocities. The change in the magnetic flux generates an induced voltage pulse. It is shown that the total induced voltage during the entire fall is constant and therefore independent of the velocity. In respect to the magnet polarity, the induced voltage changes from plus to minus or vice versa.

  • Intuitive, touch-optimized software that controls all devices simultaneously
  • Simplified implementation: all pre-settings already prepared
  • Fast and easy experimenting
  • Coil with several tappings for quick change of winding numbers
  • Investigate the influence of different falling velocities with high frequency/resolution measurements
