FIELD: training devices, possible use in laboratory practicum in physics course for studying physical laws.
SUBSTANCE: device contains solenoid, connected through current meter to harmonic voltage generator, moveable rod with indicator coil and indicator, scale, immoveable indicator coils, first switch and EMF recorded. Also, device contains a magnet core, volume of which is equal to internal volume of solenoid and may be inserted into solenoid. An additional indicator coil is positioned inside and in the middle of the magnet core. Device contains second switch for two positions, by means of which either moveable indicator coil or additional indicator coil is connected to the EMF recorder.
EFFECT: expanded functional capabilities.
