how do i re-magnetize magnetic rings and bracelets?


Put the rings and bracelets next to a permanent magnet, or I guess an electromagnet would also re-magnetize them. Moving the magnet back and forth across the rings and bracelets might help.

If they don't stay magnetized then put them next to the magnet and smack the rings and bracelets with something hard. The vibrations help the iron atoms line up which magnetizes the metal. Don't smack a magnet or the vibrations will help to randomize the atoms and weaken the magnet.
