Hi Therese, Yes it is possible to glue yourmagnet back together with common two- part epoxy. Theresulant magnet will be very close to what it was before.The problem is how to hold it until the epoxy canharden. These magnets push each other apart VERYstrongly.
Subsequently, one may also ask, can you glue magnets together?
For most surfaces, such as metal and wood, the typicalstrong adhesives such as two-part epoxies, Loctite, Liquid Nails,Super Glue, and Gorilla Glue all work well. Low temphot glue can be used with ceramic magnets – butnot with neodymium magnets. The temperature of the gluecan lower the strength of those magnets.
Thereof, why Do Broken magnets repel each other?
When a magnet is broken in two pieces, thetwo halves will repel each other. The two ends in the centerare South and North, they are different, thus in theory theyshould attract, but in real life they repel. Themagnets behave like they would have undergone a polereversal (like this: N==S S==N).
Bottom Line: Cyanoacrylates are good for projectsinvolving: wood, metal, ceramic, leather, glass, and someplastic where bond line is very tight. Hot glue: Hot gluecan be used on porous and non-porous surfaces.
