An apparatus comprising: a stator; and a rotor disposed for rotational movement relative to the stator and including: a backing member having a surface; and a flux focusing magnet attached to the surface of the backing member, the flux focusing magnet including: a center portion having a nominal angle of polarization; a first side portion disposed on the backing member on a first lateral side of the center portion and having a first angle of polarization that is less than 90° greater than the nominal angle of polarization; a second side portion disposed on the backing member on a second lateral side of the center portion, opposite to the first side portion, and having a second angle of polarization that is less than 90° less than the nominal angle of polarization, the first side portion and the second side portion configured to direct flux toward the center portion, the first angle of polarization and the second angle of polarization each converging in a direction above the flux focusing magnet to form a flux field region above the flux focusing magnet, characterised in that the backing member is formed of a ferromagnetic material, and the flux focusing magnet also including: a first end portion disposed on the backing member on a first longitudinal end of the center portion and having a third angle of polarization that is less than 90° greater than the nominal angle of polarization; and a second end portion disposed on the backing member on a second longitudinal end of the center portion, opposite to the first end portion, and having a fourth angle of polarization that is less than 90° less than the nominal angle of polarization; the third angle of polarization and the fourth angle of polarization each converging in a direction above the flux focusing magnet to form a flux field region above the flux focusing magnet, the backing member being configured to form a return flux path for the flux focusing magnet. a stator;
