Floating Graphite Disk

Product Code : SCL-EI-10674

Lab Glassware Manufacturer, based in Ambala, Haryana, has been manufacturing and exporting laboratory and physics teaching equipment since 1982, supplying schools, colleges, and research institutions across India and to international buyers including Bangladesh, Sri Lanka, Nepal, and Pakistan in the South Asia region. The Floating Graphite Disk is a physics laboratory demonstration component used for showing diamagnetic levitation and the interaction between graphite and strong magnetic fields.

Quick answer: the Floating Graphite Disk is a lightweight graphite component that can float or stabilize above a suitable arrangement of strong permanent magnets, demonstrating diamagnetism — the way certain materials are gently repelled by a magnetic field rather than attracted to it. Graphite grade, disk size, and the compatible magnet system should be confirmed with Lab Glassware Manufacturer before ordering, since reliable levitation depends on matching these specifications correctly.

Floating Graphite Disk – Specifications

Key Features

• Diamagnetic levitation demonstration showing floating behaviour over a suitable magnetic field arrangement
• Disk-shaped graphite component as confirmed by the product name
• Magnetism teaching aid for lessons on diamagnetism, magnetic repulsion, and field gradients
• Visual classroom effect that contrasts with ordinary magnetic attraction
• Suited to inquiry-based STEM experiments on materials and magnetic behaviour
• Reliable levitation depends on confirmed graphite grade, thickness, and magnet arrangement

What Is Included

Depending on the configuration ordered, the kit may include the floating graphite disk, a magnet array, a base plate, a storage case, a handling tool, an activity sheet, and a certificate. Confirm the exact contents with Lab Glassware Manufacturer before ordering.

Applications and Uses

• Demonstrating diamagnetic levitation in physics classrooms
• Showing repulsion of graphite in a strong magnetic field
• Explaining why not all materials are attracted to magnets
• Comparing diamagnetic, paramagnetic, and ferromagnetic material behaviour
• Using in STEM activities on magnetic fields and material science
• Supporting science exhibitions and teacher-led magnetism demonstrations

How to Use the Floating Graphite Disk

1. Confirm the compatible magnet arrangement and graphite disk grade before use.
2. Place the magnet array or magnetic base on a stable, flat laboratory bench.
3. Keep phones, watches, magnetic cards, and sensitive instruments away from strong magnets.
4. Use clean, dry hands or a soft handling tool to position the graphite disk above the magnet array.
5. Release the disk gently and observe whether it stabilizes or floats over the magnetic field.
6. Ask students to observe position, stability, and the effect of small air movements or tilting.
7. Compare the behaviour with ordinary non-floating objects and magnetic materials.
8. Return the graphite disk to its storage case after the demonstration.

Safety note: strong magnets can pinch fingers and damage electronics. Keep magnets away from pacemakers, magnetic cards, phones, watches, and loose iron objects. Graphite disks may be brittle; do not bend, drop, sand, or scratch the disk.

Care and Maintenance

• Store the disk in a protective case to prevent chipping and surface damage
• Handle only by the edges where possible
• Keep the disk dry, clean, and free from dust or oil
• Remove from use if cracked, warped, chipped, or unable to perform consistently with the correct magnet arrangement

Floating Graphite Disk and Related Magnetism Equipment

The Floating Graphite Disk works alongside other magnetism teaching apparatus from Lab Glassware Manufacturer. A neodymium bar magnet or a set of cylindrical magnets can supply the strong field the disk needs, while the magnetic 3D field demonstrator helps students visualize the field shape responsible for the levitation effect. Together these products build a fuller lesson on magnetic fields, attraction, and the less familiar phenomenon of diamagnetic repulsion.

Frequently Asked Questions

What is a Floating Graphite Disk used for?
A Floating Graphite Disk is used to demonstrate diamagnetic levitation and the repulsion of graphite in a suitable magnetic field.

Does the disk float by itself?
No. The disk requires a suitable magnet arrangement. Levitation depends on graphite grade, disk thickness, weight, and magnet-field geometry.

What type of graphite is required?
The graphite grade is not confirmed. Pyrolytic graphite, natural graphite, or any specific grade should be added only after checking the final product specification.

Are magnets included with the product?
Magnet inclusion is not confirmed. Magnets or a magnetic base should be listed only if they are supplied with the final kit.

Can students handle the disk?
Yes, under supervision. The disk should be handled gently because graphite can chip or break if dropped or bent.

Is it suitable for school physics labs?
Yes. It is suitable for supervised school and college physics demonstrations on diamagnetism, magnetic fields, and material behaviour.
