Pfleiderer, J. – Amer J Phys, 1969
Suggests a first-order experiment that can be used to establish the Lorentz transformation without considering the constancy of light velocity or the full set of Maxwell's equations. Involves the use of a long solenoid to create an electric field in a moving magnetic field. (LC)

Johnston, D. C.; Silbernagel, B. G. – Amer J Phys, 1969
Describes modifications of a commercially available strip-type transmission line, which makes possible reproducible measurements of standing waves on the line. Experimental data yield values for the characteristic impedance, phase velocity and line wavelength of radiation in the transmission line, and the dielectric constant of material in the…

Merrill, John R. – Amer J Phys, 1970
Describes three of many uses to which the desk-top computer has been put in the introductory physics laboratory. The three uses involve an AC circuit laboratory, an equipotential mapping experiment, and an N-slit diffraction experiment. Typical desk-top computer-produced theory plots are shown. (LC)

Peer reviewedVarney, R. N.; Hahn, H. T. – American Journal of Physics, 1975
Electrets, the electrical counterparts of magnets, are polarized dielectrics that are permanent on a scale of months. Describes procedures for making electrets out of plastic sheets like Mylar, for testing them and measuring their pole strengths, and for establishing necessary and sufficient demonstrations that they are not simply surface charged.…

Rayner, J. P. – Amer J Phys, 1970
Describes three student experiments in magnetohydrodynamics (MHD). In these experiments, it was found that the electrical conductivity of the local water supply was sufficient to demonstrate effectively some of the features of MHD flowmeters, generators, and pumps. (LC)
