Re: [MW:23948] MPI with Permanent Magnets

Your concern on reliability and sensitivity of results is very important. What is the minimum thickness/diameter for which permanent magnet can provide reliable with reasonable sensitivity results?

NO...due to XX thick material will absorb limited flux density of magnetic and create poor sensitivity. Use AC/DC stilt magnet at 75mm max distance between poles, wet method oil based medium continuous technique See ASTM listing for ref.standard. Mike henthorn Sent from Yahoo Mail on Android
