answer:There’s not enough contact area between the edges of the dowel and the surface of the magnet for the Superglue to form an effective bond. Your best bet would be an epoxy with a metal filler, like JB Weld (any hardware store sells it). You would want to use a large enough dab that the end of the dowel is actually immersed in the epoxy. I would even try to work some of the epoxy up into the dowel before attaching it to the magnet to increase the surface area working for you. Then maybe coax some of the epoxy up along the outside of the dowel near the joint for the same reason. I have had some issues with JB Weld adhering to very smooth metal surfaces, so you might want to scuff the surface of the magnet with sandpaper before bonding. I should mention that If appearance is important, the JB Weld is a dark gray color, and will be pretty visible. Also, give it a good 24 hours of curing time, preferably in a warm place, before applying any stress.
