Com Padre Digital Library: Open Source Physics: Electric Multipole Field Model
Simulation demonstrating how a point charge, a dipole, or a quadrupole shows field vectors or voltage. Change the charge and see the electric field direction and magnitude, and then record the detector values using a built-in data...

Com Padre Digital Library: Open Source Physics: Magnetic Multipole Field Model
A simulation which shows the field of a magnetic dipole or quadrupole using compass needles indicating direction and relative field strength. Change the angular orientation of the dipole, and a movable compass shows the magnetic field...
