FIELD: the invention refers to educational apparatus and may be used in laboratory practice work on physics course for studying and deepening knowledge of physical laws and phenomena. ^ SUBSTANCE: the device has a plane-table on which two contours are traced. One of them is a detouring contour enveloping the turns of the fixed coils and the second detouring contour does not envelop the turns of the fixed coil. The device has also a reducing transformer, an ammeter and a rheostat which form a closed circuit with the turns of the fixed coil, a mobile cylindrical bushing, a rod, a measuring coil, an indicator of the point on the detouring contour, a detouring indicator, a register of electromotive power, a difference measurer, an indicator of phase difference and a supporting coil. ^ EFFECT: expands the field of studying. ^ 6 dwg |
