SHIELDING OF A UNIFORM ALTERNATING MAGNETIC FIELD USING A CIRCULAR PASSIVE LOOP

SHIELDING OF A UNIFORM ALTERNATING MAGNETIC FIELD USING A CIRCULAR PASSIVE LOOP

The magnetic and electromagnetic shields are used to reduce the magnetic field in local spaces. Usually these shields are implemented in the form of a box or a cylinder. At the same time the magnetic field reduction in local spaces by means of passive loops is not considered in detail yet. So, the p...

Путем аналитического и численного моделирования исследована эффективность экранирования однородного гармонического магнитного поля при помощи электропроводящего кольца. Установлены зависимости коэффициента экранирования от радиуса кольца и его поперечного сечения. Определены параметры электропроводящего кольца, применение которого позволяет снизить действующее значение магнитной индукции на 30 %. Шляхом аналітичного та чисельного моделювання досліджено ефективність екранування однорідного гармонійного магнітного поля за допомогою електропровідного кільця. Встановлено залежності коефіцієнту екранування від радіуса кільця та його поперечного перерізу. Визначено параметри електропровідного кільця, застосування якого дозволяє знизити діюче значення магнітної індукції на 30 %.
