## Customer Reviews

### ⭐⭐⭐⭐⭐ This material is sensitive to magnetic fields.
*by A***R on July 19, 2026*

Good material reveals magnetic fields, sensitive, and a good frame. It will help me with coil winding project. Good value.

### ⭐⭐⭐⭐⭐ It makes visible the invisible
*by N***Y on May 17, 2026*

Very cool product. The magnetic fields are different than I imagined

### ⭐⭐⭐⭐⭐ Awesome toy and useful for subjective comparisons of magnets
*by C***O on April 27, 2026*

Have had a lot of fun with this product. It is geared towards stronger magnets, as it doesn't reveal data on magnetic stripes. Good for subjective comparison of magnetic strengths. Pictured: an N52 round beside a weaker (maybe N35?) rectangle.
