When it comes to sparking curiosity in the classroom, few things beat a hands-on science demonstration. That’s why we’re excited to introduce our Pyrolytic Graphite Floating Display Kit—a simple, safe, and mesmerizing way to bring the principles of diamagnetism and magnetic fields to life.

Perfect for STEM educators, science clubs, and engineering demonstrations, the pyrolytic graphite classroom kit enables students to observe a material levitate above strong neodymium magnets. It’s a classroom-ready way to transform abstract magnetic concepts into something tangible, memorable, and just plain cool.

What’s Inside the Kit

Each kit includes everything you need for the demonstration:  

  • (4) ½" x ½" x ¼" Neodymium block magnets

  • (1) 1cm x 1cm x 0.5mm pyrolytic graphite wafer

When arranged correctly, the wafer hovers nearly a millimeter above the magnets, appearing to float in mid-air. Students will be fascinated to see physics in action, without wires, batteries, or hidden supports.

What Is Diamagnetism?

Diamagnetism is a property found in certain materials that creates an opposing magnetic field when exposed to an external one. In simple terms, diamagnetic materials are repelled by magnetic fields. Pyrolytic graphite is one of the strongest naturally occurring diamagnetic materials, making it the perfect choice for this demo.

In the kit, the wafer is repelled by the magnetic field of the neodymium blocks. With careful balancing, it reaches equilibrium and levitates above the magnets. It’s an unforgettable way to visualize otherwise invisible forces.

 

Classroom Applications

The pyrolytic graphite classroom kit is a versatile tool for use in lessons and demonstrations. 

Here are a few ways to integrate it into your teaching:

  1. Introduce Magnetic Fields
    Use the kit to show students how magnetic fields work in three dimensions. The floating wafer provides a visual example of repulsion and equilibrium.

  2. Teach About Material Properties
    Compare diamagnetic materials (like pyrolytic graphite) with ferromagnetic materials (like iron). Students can discuss why some materials are attracted while others are repelled.

  3. Connect to Real-World Technologies
    Relate the demo to real-world innovations such as magnetic levitation (maglev) trains, advanced sensors, and quantum levitation experiments.

  4. Encourage Inquiry-Based Learning
    Ask students to hypothesize how changing the number or placement of magnets might affect the floating wafer, then test it together.

Why Educators Love This Demo

  • Visual Impact: The floating wafer is eye-catching and easy for students to observe.

  • Hands-On Engagement: Students can safely interact with the kit under supervision.

  • Reusable Tool: Unlike consumable lab supplies, the graphite wafer and magnets can be used repeatedly across semesters.

  • STEM Inspiration: Demos like this foster curiosity, critical thinking, and excitement about science and engineering.

The pyrolytic graphite classroom kit inspires students to ask questions, test ideas, and experience the wonder of magnetism firsthand. Whether you’re teaching physics, chemistry, or general science, this simple but powerful tool can help you bring STEM concepts to life in a way your students will never forget.

Safety Warning: Magnets can be dangerous. Neodymium magnets, especially, must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Bones can be broken by larger magnets. Children should always be supervised when using magnets.
