Note (1): Ferrite bars are fragile/brittle. Do not drop on hard floors. Note (2): Ferrite bars are relatively weak & will not magnetize nails or pins. Stronger magnets such as Nd or Alnico are best for this application.

Very pleased with the product. The magnets are good sized and have a good field to them. They seem sturdy and not easy to break. Haven't set up the viewing trays yet, but will be using them soon. Excited to have something other than a paper plate for field views.

Thanks for the feedback. We did the paper clip pickup test as outlined in Magnet Experiments for Kids after seeing an Amazon review where their ferrite bar magnets could barely lift a single paper clip. We then found they were just strong enough to demonstrate magnetic fields with iron filings.
