The z
read-only property of the Magnetometer
interface returns a number specifying the magnetic field around the device's z-axis.
The magnetometer is typically read in the reading
event callback. In the example below this occurs sixty times a second.
let magSensor = new Magnetometer({ frequency: 60 });
magSensor.addEventListener("reading", (e) => {
console.log(`Magnetic field along the X-axis ${magSensor.x}`);
console.log(`Magnetic field along the Y-axis ${magSensor.y}`);
console.log(`Magnetic field along the Z-axis ${magSensor.z}`);
});
magSensor.start();
