new Magnetometer()
new Magnetometer(options)options OptionalOptions are as follows:
frequency OptionalThe desired number of times per second a sample should be taken, meaning the number of times per second that the reading event will be called. A whole number or decimal may be used, the latter for frequencies less than a second. The actual reading frequency depends on device hardware and consequently may be less than requested.
referenceFrame OptionalEither 'device' or 'screen'. The default is 'device'.
