How to Use the Neodymium Magnet 25 x 5 mm

Place the magnet on a clean, dry, non-magnetic work surface
Keep fingers clear when bringing the magnet near steel objects or another magnet
Use a magnetic compass to identify pole direction
Place paper over the magnet and sprinkle iron filings to observe field patterns
Test attraction on iron, steel, nickel-containing objects and non-magnetic materials
Compare the effect with a ferrite magnet of similar size
Return the magnet to its labelled storage container after use

Safety note: Neodymium magnets can pinch skin, break if snapped together, and affect pacemakers, magnetic cards, watches and electronic devices. Use only under supervision in student laboratories.

Care & Maintenance

Store magnets separately or with spacers to prevent sudden impact
Keep away from moisture unless the coating is confirmed as corrosion-resistant
Do not heat, drill, cut, grind or drop the magnet
Keep away from young children because small strong magnets can be hazardous if swallowed

Building a Magnetism and Electromagnetism Module

Physics departments teaching magnetism often pair the Neodymium Bar Magnet 25 x 5 mm with the Magnetic Field Board for Student Transformer for mapping field lines, the Electric Motor Kit for showing magnetism producing motion, and the Galvanometer Attachment for Student Transformer for measuring induced current from moving magnets.

Frequently Asked Questions

What is a neodymium magnet 25 x 5 mm used for?
A neodymium magnet 25 x 5 mm is used for school magnetism experiments, polarity testing, field-pattern demonstrations, attraction tests and STEM projects.

Is this magnet suitable for school physics labs?
Yes. It is suitable for supervised school physics labs when students are warned about pinching, breakage and electronic-device safety.

What does 25 x 5 mm Ø mean?
It normally indicates a magnet with 25 mm length and 5 mm diameter. Confirm the exact shape and tolerance from the final product datasheet.

Is neodymium stronger than ferrite?
Yes. Neodymium magnets are generally much stronger than ferrite magnets of similar size, which is why careful handling is required.

Can students use it with iron filings?
Yes. Students can use it with iron filings to show magnetic field patterns, but the filings should be kept in a sealed field viewer or handled carefully to avoid mess and ingestion risk.

What should be confirmed before ordering?
Confirm the magnet grade, coating, polarity orientation, pull force, dimensions, tolerance, packing quantity and safety instructions before bulk procurement.
