Referred to as the magnetic field shielding magnetic shield, is used to attenuate low-frequency magnetic field and NJM2903V datasheet and constant magnetic field generated by interference, which inhibit the parasitic mutual inductance coupling. Inductive coupling for the mutual magnetic field coupling is the magnetic field between the conductors or circuit result of the interaction. in the current carrying wire or coil around there is a magnetic field, if the current changes, which will produce around alternating magnetic field, the magnetic field in the wire or coil is induced electromotive force, When these constitute a closed loop wire or coil induced current will be generated. Even the constant magnetic field, when the magnetic field in the wire or coil to vibrate or rotate, it will also generate induced e...
