Science on a stick: An experimental and demonstration platform for learning several physical principles

We share the design for a simple apparatus that, when paired with an Arduino processor and a computer, can be used in a wide range of laboratory measurements: observing linear kinematics, confirming Faraday's and Lenz's laws, measuring magnetic moments, and observing the effects of eddy currents. The setup is simple, inexpensive, easy to replicate, and can even be fabricated and used by students working at home.(c) 2023 Published under an exclusive license by American Association of Physics Teachers.
