Magnetometer.y

The y read-only property of the Magnetometer interface returns a double precision integer containing the magnetic field around the device's y 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. See Feature-Policy for implementation instructions.

Syntax

var magnetometery = magnetometer.x

Value

A Number.

Example

The magnetometer is typically read in the Sensor.onreading 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();
