ELECTRIC CIRCUIT
Document Type and Number:
Japanese Patent JP2015065377
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric circuit capable of not only achieving rapid demagnetization but also reducing the cost.SOLUTION: An electric circuit C includes: a coil 1 whose one end is connected to a power supply Bat side and other end is connected to the ground side; a switch 3 which is provided on the power supply Bat side or the ground side of the coil 1 and selects supply and interception of electric power to the coil 1; and two or more diodes 5 which are juxtaposed with the coil 1 and use the direction directed to the power supply Bat side as the forward direction. Based on the installation number of diodes 5, time required for demagnetization is set.
