RT;DL Seeing Magnetic Fields

This activity shows a magnetic field projectual being used to reveal the magnetic field around various configurations of bar magnets. As with all RT;DLs, this activity began as an in-class lab and has been retooled for online delivery.

I will confess that I find watching iron filings slowly align with magnetic fields on a large screen to be calmingly satisfying. I suppose it's my ASMR.

Dean, this is EXCELLENT! I especially like the "mystery configuration". I am going to steal this idea for next year if you don't mind :-)

Here's a bonus Mystery Configuration for you, Caroline. Several questions could be posed about poles P through U. Would pole Q attract or repel pole T, for example.
