Is it possible to measure the grade of a magnet? Even if you 'only' have a gaussmeter? • It is interesting to know, since neodymium magnets are expensive and it would be nice to know, if you get what you pay for. • In this video I attempt to confirm the grade on some magnets before trying to determine the grade of a questionable, cheap N52 magnet. • Let's see what it takes to determine the grade of a magnet - or at least get an indication of it... • Spreadsheet for calculating flux: https://www.supermagnete.de/eng/faq/H... • Formulas used in the spreadsheet: https://www.researchgate.net/publicat... • The F71 Teslameter donated by Lake Shore Cryotronics: • https://www.lakeshore.com/products/Ga... • Block magnets donated by supermagnete: https://www.supermagnete.com/quaderma... • My Patreon-page: / brainiac75 • Older video with more on grades: • Buyer's Guide: Grades of Magnets • Mapping field of huge magnets: • Mapping monster magnets magnetic field • Did you miss one of my videos?: / brainiac75 • FULL MUSIC CREDITS • Time code: 0:01 • Interloper Kevin MacLeod (incompetech.com) • ISRC: USUAN1100401 • Time code: 0:37 • Perspectives Kevin MacLeod (incompetech.com) • ISRC: USUAN1300027 • Time codes: 2:46 + 11:25 • Floating Cities Kevin MacLeod (incompetech.com) • ISRC: USUAN1600018 • Time code: 6:36 • Long Note Three Kevin MacLeod (incompetech.com) • ISRC: USUAN1100424 • Time code: 9:03 • Clear Waters Kevin MacLeod (incompetech.com) • ISRC: USUAN1100290 • All music above licensed under Creative Commons: By Attribution 4.0 License • http://creativecommons.org/licenses/b... • Time code: 10:47 • Mix of two tracks: • 1) The Shimmering by fran_ky (freesound.org/s/237363) • Licensed under Creative Commons 0 license • 2) Spacial Harvest Kevin MacLeod (incompetech.com) • Licensed under Creative Commons: By Attribution 4.0 License • http://creativecommons.org/licenses/b... • ISRC: USUAN1100653 • #Magnet #Grade #Brainiac75
