We use neodymium magnets in the trigger wheels we make. The magnets are secured in place with a dab of JB weld.. One of our engines regularly sees 9000 rpm and we have never lost a magnet.

Tried to secure the magnets by staking them in place, but they are very fragile and easily broken if you strike the punch to hard... so we use epoxy
