Patent abstract
A current sensing method and a current sensor are provided. The current sensing method includes the steps of: exciting a magnetic core to generate at least one pair of regions having opposite magnetization directions in the magnetic core; providing a current to pass through a sensing region of the magnetic core, so that the magnetic core correspondingly generates a magnetic field change; and sensing the magnetic field change of the magnetic core by a pickup coil wound around the magnetic core to output an output signal corresponding to the current.
