FXOS8700CQ Response to High Rate of Change of Magnetic Field Direction

Hi. I have a question regarding the FXOS8700CQ 3-axis magentometer and accelerometer.  I am considering using this sensor to detect the Earth's magnetic field in a device that can rotate as fast as 7200 degrees/s.   Can the magnetometers respond fast enough to provide an accurate measurement when the magnetic field direction is changing this rapidly?  I do not see anything in the datasheet that addresses this.  Thanks.
