China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets find extensive applications in everyday life. From electronic devices to home appliance components, magnets are virtually ubiquitous. In certain specialized applications, such as when magnetic force needs to penetrate wood of a certain thickness, selecting the appropriate magnet becomes critical.
Currently, the most recommended option is neodymium magnets, which are high-strength magnets featuring an extremely high magnetic energy product. They generate exceptionally powerful magnetic fields, making them ideal for applications requiring penetration through non-magnetic materials like wood. This material can be customized to various shapes and sizes based on customer requirements—from small round magnets to large square magnets—to meet diverse penetration needs.
Magnets can come in various shapes, such as round, with holes, or embedded in holes drilled into wood.
After testing, two circular neodymium magnets measuring 20x5mm can attract wood boards with a spacing of 21mm. Two 30x20x5mm rectangular neodymium magnets can be attracted through four 13mm (52mm) wooden boards.
In some high-end wooden furniture designs, powerful magnets are used as concealed fasteners. For instance, components like drawers and cover plates in certain pieces utilize magnetic connections. When doors or drawers approach, the magnets penetrate the wood and automatically snap into place.
Although neodymium iron boron magnets possess extremely strong magnetic fields, ferrite magnets (ceramic magnets) can also meet requirements in certain situations and demonstrate greater cost-effectiveness.
For thinner wooden boards, ferrite magnets can provide sufficient penetration, making ferrite a cost-effective choice for home decor and certain simple sealing applications.
Finally, to summarize, neodymium magnets are mainly used when magnetic force passes through wood, followed by ferrite magnets, and samarium cobalt magnets are rarely used. The specific selection needs to be based on the thickness of the wooden board and the magnetic requirements.
