"Freezing" magnetic liquid. | DIY Ferropaste, Ferrofluid, Permanent Magnetite and Resin

EASY FERROPASTE: Mix magnetite powder and synthetic motor oil until smooth and fluid-like.
I tried a variety of combinations (Kerosene, Peanut Oil, MCT Oil, etc.) but here's what worked well:
MAGNETITE POWDER: https://amzn.to/2VHzOgT
MAGNATEC OIL: https://amzn.to/3lSRTn2

For making frozen/hardened permanent ferropaste objects, I got best results when mixing magnetic powder (magnetite or iron oxide both worked for me) into 5-minute epoxy.
