Measuring the field direction of a fixed magnet
Measuring the field direction of a fixed magnet
(OP)
I am new to magnets and I have been delegated to create a fixture that can take a fixed magnet and measure the dirction of the field. The magnet strength can be as high as 1kG. Currently we do this by attempting to sit the magnet on top of a compass the exact same way everytime and record the angle the needle deflects from the earth's magnetic field. we would like to go to a digital system that can remove most of the human error from the current system. I've tried to search on Honeywell's system for a device but everything I've found had specified a +-6G max for full scale. Any help would be appreciated.

Search Philips KMZ51 for the sensor and look at h

RE: Measuring the field direction of a fixed magnet
Which way is the 0.5" washer magnet oriented? Thru the thickness (height) or across the diameter?
If the magnet is oriented across the diameter, you might want to look at getting the green magnetic viewing paper. The orientation can clearly be seen and is accurate to within a few degrees.
Or (again, if the magnet is oriented across the diameter), you can buy a cheap dipole magnet with a gap slightly larger than the diameter of the washer magnet, and then place your magnet between the poles. Your magnet will line up in the direction of the field and then can be marked. Pretty simple to do and accurate as well.
RE: Measuring the field direction of a fixed magnet
There is a problem with the green magnetic viewing paper because our magnet is epoxied into a plastic device we would not be able to place the magnet on the paper. So in order to do this we would have to remove the magnet and doing so usually results in breaking some of the magnet b/c of the epoxy. And again trying to remove human eyes from the equation to improve the reliability and repeatability of the measuring system is the reason for my question. I am in the process of reviewing the device from prex and it appears promising. Has anyone used this device before?
