Abstract: A magnetic resonance force detection apparatus, comprising: a sample carrier for carrying a sample to be tested; a magnetic field source configured to provide a magnetic field to a sample when it is carried by the sample carrier; a support for supporting either the sample carrier or the magnetic field source; a support-driving-mechanism configured to drive the support such that the sample carrier moves relative to the magnetic field source, such that 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; and a support-displacement-measuring-sensor configured to measure displacement of the support and generate a signal representative of the displacement of the support.
