Solve the falling wire problem to find terminal velocity in a magnetic field. See how motion through a magnetic field induces an emf and current, creating a magnetic force that opposes the fall ...

Explore two effective methods for finding the magnetic field of a current-carrying wire loop. This short explains the reasoning behind each approach and shows how they connect theory with practical ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...
