Magnetic sensitive electronic components

[RyanT]

Is there a reasonably comprehensive list somewhere of which electronic components I need to keep away from magnets?

The only things I've ever seen affected by magnets are magnetic storage media (obviously...), CRTs, and some mechanical or electromagnetic things like some clock movements, speaker coils, reed switches, etc. However, at least these days, I'm more worried about solid state electronic components.

In a practical sense, I'm talking about relatively weak magnetic fields, such as that produced by a small (~ 10mm x 5mm) neodymium cylinder magnet at a distance of a couple of cm or more.

I'm curious about two related failure modes, actually:

• Malfunctions in operating circuits, and
• Permanent damage to (disconnected) components

Happy Easter.

Only MEMS devices like compasses, accelerometers, gyroscopes, DLP imagers, pressure sensors, etc. I guess these aren't totally "solid state" like you asked.
Hall devices are solid state and will be affected by magnetic fields, obviously. They should not have permanent damage.

The main component I've seen effected by magnetic effects are other transformers in close proximity causing unwanted coupling/interference. Is was an issue in tube based audio preamp/amps and some RF circuits. Normal recommendation was to mount transformers 90 degrees field direction.
