Three experiments inspired by high school students´ misconceptions in the area of electricity and magnetism

Abstract

The paper describe three experiments which were inspired by often misconceptions of hihg school students in the area of electricity and magnetism. First experiment concern charge distribution at insulants, second demonstrate Coulomb´s law quantitatively, third demonstrate behaviour of a coil in a uniform magnetic field.
