Working with Neodymium Magnets
What Is the Best Way to Work With Self-Adhesive Magnets?
Clean the surface, press firmly and give the 3M VHB 4920 adhesive 24 hours (about 90% strength) to 72 hours (full strength) before loading it.
How Are Steel Strike Plates and Magnets Used Most Effectively?
A steel strike plate replaces the second magnet in a closure. Use one slightly wider than the magnet and as thick as practical.
What Materials Can I Use to Block or Shield Magnetic Fields?
Nothing blocks a magnetic field completely, but steel and mu-metal redirect it away from what you want to protect.
Can I Solder or Weld to Neodymium Magnets?
No. Soldering and welding heat a neodymium magnet far beyond its 80°C (176°F) limit. Use epoxy or a mechanical mount instead.
How Should I Glue Magnets?
Two-part epoxy works best for most projects. Clean and lightly scuff both surfaces, clamp the magnet in place and let it cure for 24 hours.
