Automation of the Cavendish Experiment to 'Weigh the Earth'
J. J. Andrews, J. S. Bobowski
We describe a simple and inexpensive method for automating the data collection in the well-known Cavendish torsion balance experiment to determine the gravitational constant . T…
Non-radiative mid-range wireless power transfer: An experiment for senior physics undergraduates
S. D. Delichte, Y. J. Lu, J. S. Bobowski
A wireless power transfer experiment suitable for senior physics undergraduates that operates between 3 and 4 MHz is described and demonstrated in detail. The apparatus consists of…
Improved Single-Crystal Growth of SrRuO
J. S. Bobowski, N. Kikugawa, T. Miyoshi +5
High-quality single crystals are essentially needed for the investigation of the novel bulk properties of unconventional superconductors. The availability of such crystals grown by…
Design and characterization of a novel toroidal split-ring resonator
J. S. Bobowski, Hiroko Nakahara
The design and characterization of a novel toroidal split-ring resonator (SRR) is described in detail. In conventional cylindrical SRRs, there is a large magnetic flux within the b…
Quantitative Stirling Cycle Measurements: P-V Diagram and Refrigeration
Y. J. Lu, Hiroko Nakahara, J. S. Bobowski
This paper describes simple modifications to a demonstration Stirling engine that allows one to make quantitative measurements of the Stirling cycle. First, we describe measurement…
Using split-ring resonators to measure the electromagnetic properties of materials: An experiment for senior physics undergraduates
J. S. Bobowski
A spilt-ring resonator experiment suitable for senior physics undergraduates is described and demonstrated in detail. The apparatus consists of a conducting hollow cylinder with a…
