-Would you have an app showing the oscillation of an electric dipole in a uniform external electric field?2022-02-14
-Could you please load this on the laptop? http://hyperphysics.phy-astr.gsu.edu/hbase/electric/equipot.html2022-03-04
-Would it be possible to twist the bulb or coils of the e/m demo to show the helix formed by the charged particles when the velocity is not perpendicular to the magnetic field? If it's possible without damaging the equipment then I'd like to request it again.2022-03-30
-For the magnetic dipole, I'd like the suspended version of the coil again if that's possible. Would that work if the coil was suspended by a string to avoid friction? No need to spend time on this now but I think a dipole demo where multiple cycles of oscillations are visible would be useful in the future.2022-04-01
-Would you have a slinky to help the students visualize what a toroidal coil looks like?2022-04-06
-No need to bring LN2 for D+15+20 because I'm not sure I'll get to it today.2022-04-18
