Barlow's wheel ideal for demonstrating Lorentz force.

• Barlow's Wheels is an impressive piece of apparatus constituted by a wheel on low friction suspensions
• Wheel does not spin when batteries are installed-This demonstrates the magnetic resistance due to electricity being applied
• 4 AA batteries are required for operation of the Barlow (batteries not included)

Barlow's wheel is an historical demonstration experiment of Lorentz force generated by currents flowing between the polar expansions of a magnet. The item is equipped with neodinium-ironboron magnets that generate a strong magnetic field over the wheel that is therefore set on motion when crossed by currents.
