Speaker Disassembly???

I was hoping maybe someone over here could help me out.

I need to take a magnet off of the back of a 5" speaker without breaking it, but can't tell if it's attached to the speaker housing with some sort of adhesive or whatever. I've got the thing apart, have taken a die grinder and tried to grind the tig welds to see if that'll let it come off, but no luck. I'm left with the magnet and the plate used to mount the magnet to the speaker housing, and if I try to force the plate off the magent (or vice versa) the magent breaks... won't work I need it whole.

Any ideas???

Does anyone know of any manufacturers that don't glue the magnets to the speaker housing???

Any help is mush appreciated.

Try getting a flat head screw driver between the magnet and the woofer housing and hit it with a hammer.

I tried that, but there's a plate between the speaker housing and the magnet... when I tried that the plate pulled away from the speaker housing.. so basically I now have the magnet with a stupid square plate with a hole in the middle attached to the magnet. I also tried tapping the plate off with a hammer / mallet / woodblock.. and couldn't get them to separate.

I smashed the magnet just to see how it was put on, and they don't appear to be molded (ie magnet was formed into the plate's holes for the tig welds) into the plate.. and I couldn't tell if there was an adhesive there.

If the damned magnets weren't so fragile I'd wail on it till it came off, but I need them intact. Besides I believe that will kill the magnets strength, won't it??? (Heard that someplace.)

Maybe soak it in gasoline to desolve the adhesive if there is any???

Do you just need a round magnet ?? A good source for those is a magnatron from a junk microwave oven. Great for magnetizing phillips head screwdriver tips.

Unfortunately I need a round magent with a hole in it.

And the kicker is I need it to be magnetized through the thickness, with the hole in the center being one polarity and the outside edge being the other.

I'm not terribly certain a speaker magnet is magnetized that way, but it's worth a shot to find out. To have what I want made is around $5000. And there's no way I could afford that and even if I could, I would have serious issues paying someone that much for a magnet when I'm just trying to help a nephew out with a science project.

......... Also I looked more closely at the one I broke and there does appear to be some sort of resin that holds the magnet in place. I'm going to try heating it up with a torch, see if maybe it'll come off then.

The magnets from a magnatron is that shape. Just not sure of polarity though.

No stuff??? THANK YOU! Going hunting for a dead microwave....
