You don't need to buy square neodymium magnets when there's a better alternative. Just take a closer look at your old CD players - the read/write heads are often equipped with magnetic strips that fit this bill perfectly! These strong neodymium magnets come with a powerful force, capable of attracting metal with ease. Plus, you'll be recycling and upcycling your old gadgets in the process!
