Description

учета вли ни  вихревых токов на результаты измерений к сигналу с интегратора 1 при помощи блока 3 прибавл ютс  измен ющиес  по пилообразному закону сигналы с блоков 4 и 5. Блок 5 запускаетс  в момент уменьшени  намагничивающего пол  до нул . Момент времени , фиксируемый блоком 6 по сигналу, поступающему с блока 3, при котором магнитна  энерги  образца достигает максимального значени , соответствует запуску блока 4. Добавление пилообразных напр жений от блоков 4 и 5 позвол ет произвести необходимую корректировку сигнала, поступающего с интегратора 1. Измер ющий блок 10, управл емый блоком 6, определ ет составл ющую магнитной энергии по индукции и напр женности , а также остаточную индукцию в образце и коэрцитивную силу.taking into account the effect of eddy currents on the measurement results, the signals from integrator 1 using block 3 add sawtooth-changing signals from blocks 4 and 5. Block 5 starts at the moment of decreasing the magnetizing field to zero. The instant of time recorded by block 6 on the signal coming from block 3, at which the magnetic energy of the sample reaches its maximum value, corresponds to the start of block 4. Adding sawtooth voltages from blocks 4 and 5 allows the necessary correction of the signal from integrator 1. The unit 10, controlled by unit 6, determines the component of the magnetic energy by induction and strength, as well as the residual induction in the sample and the coercive force.
