FIELD: the invention refers to training aids and may be used in practical work in physics course. ^ SUBSTANCE: the installation has in series connected: two flat induction coils, source of constant current, ammeter and rheostat. On a stand there are two fixed axles of rotating induction coils, on which two rigid brackets are pivotally suspended with their first ends and to their second ends are rigidly connected the induction coils placed in a vessel with liquid magnet installed on the stand provided with a scale with divisions in degrees. ^ EFFECT: the installation allows to take off dependence of Ampere force arising at interacting of the coils with current in liquid magnet from the value of this current and determine value of magnetic penetrability of liquid magnet and expands the field of researching. ^ 4 dwg |
