    smco5 disc D20x1mm having both N and S on the same face

    I see you're using one of our Gauss meters. perhaps you want to send me a couple of samples and i will check it out?

    H2S affect on Samarium Cobalt & Coating

    I am trying to research whether a FBE (Fusion Bonded Epoxy) coating would help prevent corrosion of samarium cobalt in deep bore conditions with H2S (Hydrogen Sulfide) - assuming concentration of between 5% - 30%. Any info gratefully received.

    Alnico production standards, then & now

    I have had plenty of discussions with Guitar pickup device manufacturers regarding "sound" created from different Alnico materials used, with supposedly Alnico 2 giving a "softer" sound and Alnico 5 giving a "harsher" sound. Dad tells me stories of how he was involved in the design of then...

    Samarium Cobalt Magnets in Water

    I know that SmCo magnets are pretty inert in fresh water and do not corrode. Does anybody know of any documentation to this effect? Thanks.

    The effect of Hydrogen peroxide & Sodium hydroxide on SmCo

    Thanks MagMike. The grade would probably be 2:17 although not finalised yet. There may be an option to pot the magnet. What coating would you suggest?

    The effect of Hydrogen peroxide & Sodium hydroxide on SmCo

    I have been trying to find what would happen to Samarium Cobalt compound when introduced to Liquid Hydrogen peroxide & Liquid Sodium hydroxide at elevated temperatures up to 200 deg C. Can anyone suggest what may happen to the compound "Physically" not "magnetically"

    CUTTING FERRITE

    Our business started by cutting ferrite. The only way is diamond blades with plenty of coolant. We use automated as well as manual machines. Waterjet is good but slow (the last time I checked). It is very difficult to do intracate shapes, the only way is to use a particular sintering tool or...

    finding the magnetic flux in 3D

    Take a look at http://www.cermag.co.uk/Magnetic%20Scanner.htm if that is how you want to view flux lines.

    Measuring the field direction of a fixed magnet

    There are pieces of equipment that scan and display the flux lines of magnets. http://www.cermag.co.uk/Magnetic%20Scanner.htm

    Using Neodymium Magnets with N to N poles for a long period of time.

    As MagMike says, the orientation of the reed switch is important. Are you using an "end-on" or "parallel" reed switch?

    Using Neodymium Magnets with N to N poles for a long period of time.

    Magnetically, there is not enough field in either of the magnets to demagnetise or reverse the polarities of themselves. As the guys have allready mentioned, heat and corrosion should be your biggest concearn.

    Does Neutron Radiation affect Ferrite/Ceramic Magnets?

    Thank you all for your input. I now have the basic information I was looking for.

    Does Neutron Radiation affect Ferrite/Ceramic Magnets?

    Does anybody know if neutron bombardment of Ferrite/Ceramic permanent magnetic material will cause any irreversible/irrecoverable loss in the magnetic field. If so why?
