Magnetic field detection?
Are there any miniature devices to detect magnetic fields without using another magnet?
Eg. want to detect a magnet embedded into a wall.

Good thinking Pete.
Can these Hall Effect Switches work whilst in motion and can these be bought off the shelf?
Best I found after I did the post was a Magnetometer and they are huge.
As you very well know space is impotant when designing

Power Components of Midwest
Look through RS Compts and see whats available - try and get a sample to test!

Cool.
My probation period is looking safer by the day
I think this is gonna be the component to do the job. As you sai I just need a sample
Do you know any electronic/mechanical companies or contract engineers

It works for me, they cannot be too helpful - they know that if I name them on the Parts List they can then claim that they supply the UKs Number 1 Nuclear Defence company with parts ........... not a bad talking point for their next client!!

Don't think I'll have that much pulling power but they could be claiming they supply to the worlds largest c***** manufacture and the 4th or 6th richest man in America

Connect a coil to a sensitive galvanometer and move it around in the area you want to check. You would have to calibrate it to the Earth's magnetic field first of course.

I was going to suggest a compass, but realised it was another magnet !
Try Farnell HONEYWELL SS40A (1082268)
3 leg device at 85p each

Do a search and find a company in your area - tell them that you are specifying components for a big project and think their components will be ideal, could they spare a sample.
