- Boček V.: Magnets and Inductors with Current, Fair 23, České Budějovice 2018
The forces affecting a magnet placed in the magnetic field of the coil, the so-called electromagnetic pendulum, are investigated in this paper. By consecutive turning on and off of the current flowing through the coil, we will look for the resonant frequency of the pendulum.

A collection of simple experiments from the field of mechanics, oscillatory motion, acoustics and optics conducted with cheese boxes.
- Kundracik F.: The mystery of pipe acoustics, Fair 18, Hradec Králové 2013
The paper provides information on the basic principles of the formation of tones in pipes and their tuning. It also presents some ideas for making simple pipes.
- Piskač V.: Three new experiments, Fair 12, Praha 2007
The first part of this contribution is a demonstrative experiment –a light bulb rheostat changes a current in a circuit. The second part deals with acoustic devices (Seebeck siren and monochord), demonstrated by electromagnetic detectors.
- Reichl J., Dvořák J.: Ruben’s tube, Fair 23, České Budějovice 2018
The paper describes construction of a device that is suitable for demonstration of gas compressibility by acoustic waves, demonstration of standing waves, sound propagation in gas, … The device originated on basis of a gifted student Jakub Dvořák’s preparation for practical physics homework.
- Vícha V.: The Propeller in Lab Exercises, Fair 8, České Budějovice 2003
Three ideas for laboratory exercises (Rotation movement, Propeller and a monitor, Draw force of a propeller) and one problematic experimental task (Propeller as a balance wheel) with a simple propeller.
