Discover Lorentz force without using mercury.
Barlow's wheel is a 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 in motion when crossed by currents.
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).
