Abstract
A magnetic resonance force detection apparatus, comprising a sample carrier for carrying a sample to be tested, a magnetic field source and a support for supporting either the sample carrier or the magnetic field source. The magnetic field source is configured to expose the sample to a magnetic field by simultaneously providing a plurality of volumes in which the magnetic field is configured to cause the spins of one or more nuclei or electrons in the sample to flip, and wherein the flipping of spins exerts a force on the support. The apparatus also comprises a support displacement measuring sensor configured to measure the displacement of the support and generate a signal representative of the displacement of the support, and a processor configured to process the signal representative of the displacement of the support in order to determine a component of the displacement of the support caused by one or more of the plurality of volumes.
