What is the primary function of the magnetometer in the Microbit?

• Measuring temperature

• Measuring light intensity

• Measuring magnetic field strength and direction

• Measuring sound levels

How do you calibrate the Microbit to use it as a compass?

• By shaking the Microbit until it displays a checkmark

• By rotating the Microbit in different directions until all LEDs are lit up

• By pressing buttons A and B simultaneously

• By connecting the Microbit to a computer and running a special calibration program
