did the job
i bought them to block off the airways on my "compliant" wood burner so i could shut it down. it worked with three magnets left over.
Product code: 12041
This ferrite block magnet has a 50mm length, a 19mm width and a height of 4.9mm. This ferrite magnet has a magnetic flux reading of 1988 Gauss and a pull force of approx 500 grams. It is identified by the AMF magnet part number 12041.
Smaller ferrite block magnets are commonly used in DC motors, as sensors and in various hand crafts. Any machining of ferrite blocks must be done with a diamond wheel, ideally before magnetisation, as they are hard and brittle.
