Classification: CPC G | IPC G

Claim 0:
1. A magnetic relaxometry measurement apparatus, comprising:
a magnetizing system configured to supply a pulsed magnetic fields to a sample; a sensor system configured to detect magnetic fields produced by induced magnetization of the sample after a magnetic field pulse from the magnetizing system; and one or more compensating coils configured to suppress generation of eddy currents in an environment surrounding the apparatus due to the pulsed magnetic field,
wherein the magnetizing system is configured to provide magnetization pulse sequence comprising a magnetizing field of a first magnitude on for a first time and off for a second time, to use the one or more compensating coils to provide a compensation pulse of a third magnitude on for a third time and off for a fourth time, and to use the sensor system to detect a magnetization of the sample during the second time.
