Koudelková V., Dvořák L.: Three experiments inspired by secondary school students’ misconceptions about electricity and magnetism, Fair 18, Hradec Králové 2013The contribution describes three experiments which were inspired by the very frequent secondary school students’ misconceptions about electricity and magnetism. The first experiment relates to a charge on an insulator, the second one demonstrates qualitatively Coulomb’s law and the third experiment illustrates behaviour of a coil in a homogeneous magnetic field. The misconceptions are described as well as are the results of research that demonstrate a relevant misconception for each experiment respectively.
