This pack of four ferrite bar magnets, each measuring 16mm x 4mm x 50mm, features clearly identified North and South poles with a durable painted coating. Designed for safe, educational use, these weakly magnetized bars are perfect for students and teachers to explore basic magnetic principles through hands-on experiments with ferrous materials.

## Description

These ferrite bar magnets are instantly recognisable and are great for teaching children about the basics of magnetism. They are ideal for performing simple experiments with ferrous items such as iron filings and paperclips and for displaying the attracting and repelling effects of magnets.

Review: Worked well. - I would have liked to have seen these with slightly more 'magnetism' within them. However, they did work for the 'magnetic field' experiment and for teaching the about the earth's magnetism.
Review: Very weak magnets - I get more from fridge magnets - Very weak magnets. Would definitely not recommend these.
