Изобретение относитс к области магнитных измерений и может быть использовано дл измерени коэрцитивной силы магнитных материалов как в разомкнутой, так и в замкнутой маг. нитной цепи.The invention relates to the field of magnetic measurements and can be used to measure the coercive force of magnetic materials in both open-ended and closed-circuit mag. nitty chain.
Известно устройство дл измерени коэрцитивной силы, содержащее источник тока, катушку намагничивани , измерительный шунт, измерительную ка-,Q тушку, интегратор, нуль-орган, регистрирующий прибор. Коэрцитивна сила определ етс регистрирующим прибором по величине напр жени на измерительном шунте в момент равенст- ,5 ва намагниченности или индукции нулю р .A device for measuring the coercive force is known, comprising a current source, a magnetizing coil, a measuring shunt, a measuring cage, Q carcass, an integrator, a zero-organ, a recording device. The coercive force is determined by a recording device by the magnitude of the voltage across the measuring shunt at the moment of equal, 5 VA magnetization or zero induction p.
Недостатками данного устройства вл ютс ограниченна точность изме- 20 рени при измерении в разомкнутой магнитной цепи, а также потери мощности , возникающие в измерительном шунте.The disadvantages of this device are the limited measurement accuracy when measuring in an open magnetic circuit, as well as the power loss occurring in the measuring shunt.
Измерйема величина в нем опреде- л етс после определенного количества циклов перемагничивани и соответствующей обработки.- Количество циклов перемагничивани посто нно и определ етс точностью измерени и диапазоном измерени регистрирующего прибора f 2 J.The measurable value in it is determined after a certain number of cycles of magnetization reversal and the corresponding processing. The number of cycles of magnetization reversal is constant and is determined by the measurement accuracy and the measuring range of the recording device f 2 J.
Известно также устройство дл измерени коэрцитивной силы магнитных материалов, содержащее блок управлени , выход которого через .блок намагничивани подключен к индукционной катушке намагниченности образца, интегрирующий усилитель и три ключа .It is also known a device for measuring the coercive force of magnetic materials, comprising a control unit, the output of which is connected via an magnetization unit to an induction coil of the sample magnetization, an integrating amplifier and three switches.
