Product code: 20020
This rare earth disc has a diameter of 15mm and a height of 7mm. It has a magnetic flux reading of 4298 Gauss and a pull force of 6kg. It is identified by the AMF magnet part number 20020.
Rare Earth discs of these dimensions are approaching the cylindrical shape, providing more concentration of the pull or repelling force through the axially magnetised flat pole surfaces. The increased thickness dimension increases the magnetic strength of the magnet. Applications include Metal separation and decontamination, water conditioning and purification, metal detectors, tool and knife holders, metal or timber wall stud and noggin detectors, magnetic healing therapy, magic tricks and invisible brochure and protective jacket closures.

Haven’t used them yet. Going to recess them into some double swinging timber screen doors to hopefully make them both line up and also stop the wind blowing them open. Don’t know if they will be strong enough yet, the doors have 3 large spring hinges each, so will see what happens. May have to buy some stronger ones.
Purchased magnets to keep oven door close, since then found out they will lose their magnetism over time because of the heat, but they are doing find at the moment.
AMF Magnetics reply: Hi Evie, thank you for your review! Yes you're right, Neodymium Magnets can lose their magnetism above 80°C but this is where Ferrite Magnets are great – they can withstand temperatures up to 250°C.
Was used to make a door stop on our caravan. Worked perfectly.
Excellent product - so useful. Using magnets to hold a reptile vivarium lid closed.
I stuck magnets to the underside of the tanks glass lip - & stuck magnets to the framed mesh tank lid... magnets attract through the glass lip & voila... tank lid stays in place (snake can't push the lid up :)
