Maxwell Wheel
Product Code : LSK-AM-11108
Maxwell Wheel (SKU LSK-AM-11108), also called the Maxwell disk, demonstrates the law of conservation of energy: as the wheel is released and falls, its potential energy is converted into kinetic energy of motion and spin, and that energy carries it back up again. It suits Class 11 and undergraduate mechanics teaching. The wheel is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which supplies schools, colleges, tender contractors and distributors directly from the factory.
Specifications
The table below lists the defined details of this model. In short, it is a Maxwell disk for showing that potential energy turns into kinetic energy as the wheel descends; dimensions, mass and frame details for the unit you order are confirmed on the quotation.

Applications and Experiments for the Maxwell Wheel
A Maxwell wheel is a heavy disc on an axle that hangs from two cords wound round the axle. When it is let go it drops, spinning faster and faster, then climbs back up the cords, showing students in a single motion how gravitational potential energy changes into kinetic energy.
- Class 11 physics, work and energy: illustrating that the total mechanical energy stays nearly constant as height falls and speed rises.
- Class 11 rotational motion: dividing kinetic energy between translation and rotation, with the descent timed on a Digital Stopwatch.
- B.Sc. and engineering mechanics: estimating the moment of inertia from the drop height, fall time and an axle diameter read with an Electronic Digital Vernier Caliper.
- Discussing energy losses through friction and air resistance from the gradually smaller height reached on each rebound.
Wind the cords evenly so the axle stays horizontal, and keep hands clear of the spinning disc.
Standard Scope of Supply
The Maxwell Wheel is supplied as a single unit as described above, ready for energy-conversion demonstrations. Any optional accessories, such as a stopwatch for timing the fall or a vernier caliper for measuring the axle, are listed separately on the quotation and can be ordered together with the wheel.

Frequently Asked Questions
What does the Maxwell wheel demonstrate?
It demonstrates the law of conservation of energy. As the wheel falls, its potential energy is converted into kinetic energy, and as it climbs back up the cords that kinetic energy is turned back into potential energy.
Why does the wheel not return to its starting height?
A little energy is lost on each cycle to friction in the cords and axle and to air resistance, so every rebound is slightly lower. Students can use this loss to discuss non-conservative forces.
Where can I check dimensions for a tender?
Send your tender specification through the contact page. Science Lab Supplies will reply with an item-wise quotation stating the dimensions, packing, delivery time and price of the Maxwell wheel it will supply.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer of this wheel. Production takes place in its own factory in Saha, Ambala, India, and buyers receive quotations directly from there, without a trader adding a margin.
