Hello mates, my question is that where can I find neodymium magnets that is already in my home, office or school? Can it be in a hard disk? Can it be in a Computer Monitor, TV? Please help, I need it for our science exhibit to show a homopolar motor, I don't like buying through the internet....

Finding those magnets in a "resourceful way"
is likely to cost you a hellofa lot more than
buying them OTC.
The owners of the equipment might object
rather strenuously.

Neodymium is used in the strongest permanent magnets known - Nd2Fe14B. These magnets are cheaper, lighter, and stronger than samarium-cobalt magnets. Neodymium magnets appear in high-quality products such as microphones, professional loudspeakers, in-ear headphones, Dokodemo Magnets, guitar and bass guitar pick-ups and computer hard disks where low mass, small volume, or strong magnetic fields are required.
