Designing High School Lenz's Law Experiment

  1. Apr 1, 2009 #1
    I teach high school physics and I would like to get maximum mileage out of my Lenz's law experiment/demonstration.

    I am going to get the students to drop magnets down a long copper tube to calculate the magnetic force using distance, time etc and making a direct calculation using Fnet=...

    What I'd also like to be able to do is use this set-up in some way to calculate the magnetic field strength of the magnets.

    Can anyone think of a way to achieve this without the addition of a lot of extra equipment?

    Thank you. That is a good demonstration.

    I am planning to use long copper tunes to show the slowing effect due to the opposing fields and was wondering if I could incorporate this set-up and get to the strength of the magnets through that.
