Modeling the induced voltage of a disk magnet in free fall
N Samboy - American Journal of Physics, 2023 - pubs.aip.org
We drop a circular disk magnet through a thin coil of wire, record the induced voltage, and
compare the results to an analytic model based on the dipole approximation and Faraday's …
