okay guys, i think I am out of my depth on this problem.
Im doing a long investigation on eddy currents, and i derived a formula. I am reaching the end of the investigation, and so i wanted to compare my experimental data to expected data. One of the factors i was investigating is the relationship between the terminal velocity of a magnet and its magnetic field strength in the scenario where a magnet is dropped down a copper tube.
However, as the magnet was too strong for my magnetic field measuring probe to measure, i measured it at 1 cm away from the magnet.
Is there any equation that can determine the actual magnetic field strength of a magnet, from the magnetic field strength of a magnet at 1 cm away.
Also, just as a side note, is there any way to determine the height of eddy currents algebraically. I know that the height of the eddy currents is the cross sectional area of the eddy currents divided by the thickness of the conductor. (ie h=A/z), but how do you determine the cross sectional area of the eddy currents.
Thanks so much!
