The rare earth magnets are pretty strong and with enough of them properly placed the door should stay in place. Having said that, I think my first consideration would be to attach the door with hinges and use the magnets to hold it closed. I think that under actual use you will find this to be more convenient rather than have the door come completely off. Just my $0.02 worth.

You need neodymium magnets. They come it all kinds of sizes and are up to 10 times stronger than regular magnets. Should be no problem using them. Epoxy them to surface and and small metal plate for other piece (door, box) and your good to go.

I would just make bottom piece a little wider so door would sit on it the 2 magnets should be perfect :<))

You could easily hold that size piece of wood on with magnets. Like the others have said you want rare-earth magnets—they are the strongest.

I’ve purchased magnets from this place > https://www.kjmagnetics.com/

You can epoxy the magnet into a hole or recess. You can also buy magnets that have a countersunk hole cast into them—so you can put a screw through the magnet to attach it. They also sell small cups that are can be mounted and are designed to hold a magnet

I will reveal my secret magnet source – Harbor Freight. They sell a pair of magnetic hooks for usually $4.99 with a 20% discount coupon. The package says they have 65 lbs of pull. I believe it! They come back-to-back with a piece of foam in between. Be careful when you take them apart. If you get your thumb pinched between them you can get a pretty nasty blood blister. DAMHIKT. Simply drill out the hooks (1/4” drill) and attach with bolts or screws to whatever you want to hold. I’ve used them all over my shop. I have 3 of them holding a 2’ x 2’ pegboard under my cast iron table saw wing with ALL my table saw accessories hanging on it. They are strong, cheap, and reliable.

I recently purchased some magnets from Amazon for totally unrelated purpose. I constantly laughed at myself as I worked to separate each one as I used them. I finally had to use a table knife to pry them apart. Lifting them or sliding them was fruitless. They are 2” long and 3/8” wide. They come with very good 3m double sided tapes pieces cut to the magnet size. Maybe they might be what your are considering. The cost was good too. 24 for $20.

If you have questions about magnets, lew posted the link to the right company, KJ Magnetics!
If they don’t have what you want/need, it doesn’t exist.

They helped me do a magnetic tracking system for a wind driven car.

Thanks all, sounds like rare earth magnets are the way to go.

@Gr8hunter: Good idea, but I’m thinking I want a clean look and I think doing it your way will add a seam where the face is sitting on another piece of wood. Hopefully that makes sense.
