The x read-only property of the Magnetometer interface returns a double precision integer containing the magnetic field around the device's x axis.

If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. The Feature-Policy HTTP header article contains implementation instructions.

Examples

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();
