 Operation of magnetometer is based on application of magnetoresistive effect when electrical resistance of a conductor is fluctuating in correspondence with magnetic fields pattern direction. Sensor operation is based on a layer of permalloy (special nickel-iron alloy) possessing a strong magnetoresistive effect. Electrical resistance of permalloy usually fluctuating within the range of ±5 % depending on force and pattern direction of magnetic field. Operation of magnetometer is based on application of magnetoresistive effect when electrical resistance of a conductor is fluctuating in correspondence with magnetic fields pattern direction.

 Therefore measuring the electric current force flowing through the layer of permalloy at the permanent current of +5V it is possible to determine the direction of magnetic fields pattern. To measure the magnetic field pattern direction by all three axes three little sensors are utilized oriented along axes X, Y and Z , installed in one microchip. Therefore measuring the electric current force flowing through the layer of permalloy at the permanent current of +5V it is possible to determine the direction of magnetic fields pattern.
