Vector Arrow

Magnetic vector arrow to help electromagnetism students understand notation for a vector going “into” (X) or “out of” (O) the whiteboard.

I remixed the ‘3D Vector’ model by Runningrandall (Thingiverse: https://www.thingiverse.com/thing:4701414 ) — making the vector longer, changing the shape of the arrowhead and fins, and sizing the spaces to fit two 6x2mm magnets. I added two color changes to accentuate the ‘X’ and ‘O’ on the vector arrow. No supports required.
