Device used to determine aircraft direction by using magnetic field is called
A
mechanical compass
B
thermal compass
C
earth inductor compass
D
magnetic compass
Explanation: 

Detailed explanation-1: -The magnetometer, also known as a magnetic sensor, is a sensor for measuring magnetic induction (magnetic field intensity), which is an important sensor component in all types of aircraft and spacecraft.

Detailed explanation-2: -Two basic types of compasses are in current use: the magnetic and gyrocompass.

Detailed explanation-3: -Magnetometer. Since the accelerometer can only measure pitch & roll, a magnetometer provides an AHRS with a measurement of yaw by comparing the measurement of the magnetic field surrounding the system to Earth’s magnetic field, just like a traditional magnetic compass.
