The magnetometer is another first for the SRP program. The magnetometer was designed and built by the SRP program of the University of Tokai in Japan as part of a new collaboration between the two student rocket programs. The magnetometer will be on both TR1 and TR2 to measure the rocket's orientation. The magentometer measures strength of the magntiude in three directions relative to the rocket. These measurements can be used to find important data such as the rockets orientation, spin rate, and precession.  

    The magnetometer is a complex board that measures the magnetic field around the rocket. The operating concept is based around measuring the offset in the B-H curve resulting from any magnetic fields present near the rocket. A ferrite core is driven into saturation with a drive coil at 9.6 kHz. The resultance flux in the core is picked up with a pickup coil. Because the core is in saturation (therefore non-linear) it creates harmonics of the 9.6 kHz. The 19.2 kHz harmonic's amplitude is used in a straightforward fashion to measure the offset mangetic field.   

   Built by Chikara Furukawa and his magnetometer team at Tokai University, this board will greatly improve the data obtained with the test rockets to better characterize the performance of the test flights.
