Abstract
Example embodiments of the present invention provide 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; one or more compensating coils configured to suppress generation of eddy currents in an environment surrounding the apparatus due to the pulsed magnetic fields.

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.
