Before transforming to pearlite, this material phases through the two-phase zone (yellow) between austenite and ferrite. In cooling through this zone, ferrite is precipitated on the austenite grain ...

That’s why today we’d like to introduce you to a new product, The Hackaday Passive Aligned Ferrite Active Quantum Crystal Nanoparticle Reference Sticker. Here’s the problem: we’re ...

The sensor uses a ferrite core and a hall effect sensor. The ferrite toroid is split in half, one half in each side of the clamp. An opamp circuit provides a gain of 100 to boost the hall effect ...
