Fun parts inside old parts

Before you throw out your old, dead hard drives, dismantle them and recover the magnets inside.

Some of the most powerful magnets known to man are inside.

A couple of cute little motors too, but they don't like to come out easily.

I agree, just don't put the magnets together with your fingers in the middle of them !

Next all I need to do is get the destructions to build a generator with them.

Any electrical geniuses in the forums?
