Magnet FAQ
Twenty-five questions people actually ask about magnets: how they work, where their energy comes from, whether they wear out, what they do to a phone, and whether any of it is dangerous. Plain answers, written by someone who has made the material.

What is a magnet?
One word covers three very different things: materials that amplify a field, materials that remember one, and coils that make one from current. This maps the whole family, from iron and silicon steel through ferrite, alnico, SmCo and NdFeB to superconducting coils and the materials still on the drawing board.

Illustrated walkthrough, thirteen process steps
How magnets are made: mine to magnet
A sintered neodymium magnet passes through thirteen distinct processes between the ore body and the finished part, and each one has to be tuned to the ones on either side of it. This walks the full chain, with an animated figure for every step and the mass yield that survives it.

Reading a B-H curve
Every magnet datasheet leads with four numbers and one plot. This builds them up from empty space, through soft iron, to a sintered NdFeB magnet, so Br, Hcb, Hci and (BH)max each mean something.
