We used the magnets off of an old nikken mattress pad.
2800 gauss grade 5 ceramic.
The manufacturer lists this on the product.
This tool calculates magnetic field strength measured in gauss on the centerline of a disc magnet or ring magnet magnetized through its thickness at a distance of x from the surface of the magnet.
This ceramic 8 magnet is stronger than a ceramic 5 magnet of equivalent size.
These are receptive to most adhesives including hot glue e6000 goop.
Have questions or comments.
The surface field is the strength of the magnetic field measured right at the surface of the magnet.
These are high quality and very strong for their size.
Can be glued onto any surface.
You can find disc magnets almost anyplace that sells magnets.
Ceramic magnet material is extremely brittle and can chip or break if dropped on a hard surface or if allowed to jump at an attracting object.
And international 1211 atchison court castle rock colorado 80109.
Using to hold small handmade ceramic pieces.
Ceramic magnets or ferrite are made of a sintered composite of powdered iron oxide and barium strontium carbonate ceramic.
Due to the low cost of the materials and manufacturing methods inexpensive ceramic magnets or nonmagnetized ferromagnetic cores for use in electronic component such as radio antennas for example of various shapes can.
Grade n42 magnets have a br of 13 200 gauss while n52 magnets can be as high as 14 800 gauss.
The weakest grade of ceramic material is grade 1 which is typically non oriented.
These calculations are only appropriate for square loop or straight line magnetic materials such as ceramic magnets neodymium magnets and samarium cobalt magnets.
This magnet is a great item for science projects and craftings.
2800 gauss grade 5 ceramic great for all craft and hobby applications.
Power force 2800 gauss grade 5.
These magnets were made under the iso 9001 quality system.
This disc ceramic magnet is made of grade 8 hard ferrite and is axially magnetized.
See our specs page for more br values for various neodymium magnet grades.
Make sure that north is facing in for all of the magnets that you attach.
Round ceramic industrial ferrite magnets d18xt4mm standard disk ceramic magnets round hard sintering ferrite permanent magnets for hobbies.
These inexpensive disc magnets are commonly called ceramic craft magnets and are solid strontium ferrite discs.
Short experience so far update.
Reasonable strength for size.
I use them to epoxy to back of ceramic art pieces i make that are used as refrigerator magnets.
