thanks all, for the comments.
my intent was to try to reuse. some magnets that i run into from old electronic devices. so my first thought was to melt the magnets and reshape them to later use.
I had read in some sites that piling up "hard drive disc" magnets together will strength their field.
in my current state I don't have any access to almost any kind of machinery. as a DIY enthusiast I have started to try to make a windmill has a protect. but before spending like 2 thousand dollar in pieces I want to construct I test project for the sake of learning.
my haul consist of
many radios speakers,TV,a microwave and a couple of hard drive.
I don't mean to be stingy. sure there are a started kit some where fairly cheap.
but I really want to try to reuse what. I have read for about 3 months and I think it is time to move to experimentation.
also I'm short on tools.since melting and reshaping is out of question.
so I ask.
cutting and piling together pieces of magnets will do it? most speakers have ring magnets. so can I cut them and pile pieces together to achieve a stronger field?
regards.
