Title:
MAGNETIC DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/218626
Kind Code:
A1
Abstract:
In a magnetic detection device (10), an influence rate determined in accordance with Expression (1) shown below satisfies a condition represented by Expression (2) shown below. Expression (1): Influence rate [%] = (((N1 + N3)/(N1 + N2)) − 1) × 100
Expression (2): −7.00 [%] < Influence rate [%] < 7.00 [%]
N1 represents a magnetic flux density in a magnetic detection unit (13) due to a current flowing through a first conductor unit (21). N2 represents a magnetic flux density in the magnetic detection unit (13) due to a current flowing through a second conductor unit (22). N3 represents a magnetic flux density where an error between N3 and N2 is maximum, assuming that the second conductor unit (22) is moved to four different locations each with a 1.5 mm shift in X and Y directions.
