Horseshoe Magnet 50mm

Product Code : SCL-AM-12110

The Horseshoe Magnet 50mm is a U-shaped permanent magnet used for demonstrating magnetic field lines, pole properties, and magnetic attraction forces in educational classrooms. Designed for science teachers, students, and lab instructors, this compact tool provides a powerful visual aid for foundational physics training.

Product Description

The Horseshoe Magnet 50mm from Science Lab Supplies is constructed from a premium ferromagnetic alloy to ensure a strong, long-lasting magnetic flux density. By bringing the opposite north and south magnetic poles closer together in a classic U-shape, this tool produces a concentrated magnetic field between the poles that yields clearer experimental data than standard bar variants.

This rugged classroom resource withstands consistent student handling during group laboratory activities. The poles are cleanly stamped with 'N' and 'S' indicators for immediate identification, and the device comes equipped with a soft iron keeper plate to protect the magnet from demagnetization over time. This essential tool integrates seamlessly with basic physics lab equipment configurations.

Key Features

• High-Coercivity Alloy Core: Fabricated from a strong ferromagnetic material to resist accidental demagnetization from mild drops or structural impacts.
• Concentrated U-Shape Field: Brings the North and South poles within close proximity to create a stronger, highly localized magnetic force.
• Stamped Pole Indicators: Permanently engraved or painted with clear 'N' and 'S' letters to ensure easy student identification during labs.
• Soft Iron Keeper Included: Supplied with a protective iron armature plate to maintain magnetic alignment during storage.
• Compact 50mm Length: Ideal sizing for small-group hands-on activities, tabletop sorting tasks, and easy organization within standard inventory drawers.
• Durable Protective Finish: Features a high-visibility red and blue enamel finish that prevents structural corrosion and shields the alloy from moisture.

Technical Specifications

Applications / Uses

• Mapping magnetic field lines on cardstock using iron filings or small plotting compasses.
• Demonstrating the laws of magnetic attraction and repulsion with nearby ferromagnetic objects or companion bar magnets.
• Serving as a fundamental component inside custom student science kits and STEM modules.
• Conducting weight-lifting experiments to determine how much mass a 50mm permanent magnet can pull against gravity.
• Providing dependable reference materials for verifying induction concepts in general laboratory instruments.

How to Use the Horseshoe Magnet 50mm

1. Remove the Keeper: Slide the soft iron keeper plate horizontally off the two poles before starting your experiment.
2. Identify the Poles: Observe the 'N' and 'S' indicators to orient your magnetic circuit correctly.
3. Map Field Patterns: Place the U-shaped magnet flat under a sheet of acrylic or paper, sprinkle fine iron filings on top, and tap gently to visualize the field lines.
4. Test Attraction Force: Place paperclips, pins, or small steel washers near the poles to measure the lifting distance and capacity.
5. Reapply Protection: Slide the soft iron keeper plate back across both poles when the experiment concludes.

Safety Note: Keep this permanent magnet away from electronic media, pacemakers, and high-sensitivity digital instrumentation to prevent signal corruption.

Care & Maintenance

• Always Use the Keeper: Keep the soft iron keeper plate firmly attached across the poles during periods of non-use to preserve magnetic flux.
• Avoid High Impacts: Do not drop the magnet onto concrete floors or strike it with heavy tools, as severe mechanical shock can misalign domains and cause demagnetization.
• Keep Away From High Heat: Do not expose the magnet to open burner flames, as heating past the material's Curie point permanently strips its magnetic field.

Frequently Asked Questions

How does a Horseshoe Magnet 50mm differ from a standard bar magnet?

The U-shape brings both magnetic poles onto the same geometric plane, creating a highly concentrated magnetic field between them that allows for much stronger lifting capabilities than a straight bar magnet.

Why does this permanent magnet include a soft iron keeper plate?

The soft iron keeper plate acts as a closed circuit loop for the magnetic flux lines, which prevents external magnetic fields or mechanical disruptions from demagnetizing the alloy core during long-term storage.

Can I use the Horseshoe Magnet 50mm near consumer computers or smartphones?

No, you should maintain a safe distance of at least 30 cm from electronic storage media, digital screens, and magnetic strip cards to prevent accidental erasure or component damage.

What is the specific composition of this U-shaped magnet?

This magnet is built from a high-quality ferromagnetic steel or Alnico alloy, ensuring a high level of magnetic remanence and excellent structural rigidity for educational settings.

How can I cleanly map out the magnetic field lines with students?

You can place the magnet directly under a clear sheet of plastic, dust a uniform layer of fine iron filings over the surface, and tap the sheet lightly to see the field arcs form clearly from pole to pole.
