Set Of 5 Block Magnets 50 mm
Five magnets, all 50x15x6 mm, all magnetised through their lengths, but in spite of same measurement enormously different:
1 of ferrite: quite weak and undefined poles
1 of ferrite: quite weak and poles marked
1 of alnico: quite strong and undefined poles
1 of alnico: quite strong and poles marked
1 of neodymium: really strong, without any marks
| Determination of holding force: | Holding force measured on constructional steel (min. 10 mm). Other metallic bonding surfaces or influences (e.g. air humidity, dust, vertical position, outdoor use) might reduce holding force. 1 kg ≈ 10 Newton. |
|---|---|
| Handling: | Magnets can break or shatter in an uncontrolled collision. |
| Height (H): | ~ 6 mm |
| Length (L): | ~ 50 mm |
| Material: | AlNiCo, NdFeB (neodymium), SrFe ([hard] ferrite) |
| Net Weight: | ~ 208 g |
| Safety information: | This is not a toy. Inappropriate use might cause injury. |
| Tolerance: | ± 0.3 mm |
| Width (B): | ~ 15 mm |
