Induced voltage pulse and Faraday’s law of induction with Cobra SMARTsense
Article No: P2441265
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. Benefits 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 Tasks Observation of the induced voltage pulse during the fall of the magnet through the coil Observation of the induced voltage for an inverted magnet polarisation Evaluation of the influence of the number of windings on the induced voltage Evaluation of the influence of the fall height on the induced voltage Learning objectives Induced pulse Faraday's law of induction Maxwell's equations Magnetic flux Magnetic flux density Magnetic field lines Operating system-independent software included.
