WebUse the magnetic scalar potential Vm for a magnetic sphere in a uniform external magnetic field. Consider a sphere of radius R made of (arbitrary / unspecified) linear magnetic material of magnetic permeability μ=+μχom()1 placed in the gap of a big electromagnet that produces a uniform external magnetic field ˆ Bext o=Bz G Web12 apr. 2024 · In the case of single sensor (A), the noise of conventional magnetometer is limited by both PSN and common-mode magnetic field noise (CMMN).For the conventional gradiometer (B), the measured CMMN of the two sensors is identical, while the additional quantum noise (AQN) is uncorrelated.With differential measurement, the CMMN is … WebIt is now possible to split the equations of motion at different orders of ϵ. Starting from the leading order, namely ϵ−2, we can select these terms from equations (3.14) and (3.15) (actually only one term from the scalar and one from the tensor perturbation), then plug them in eq.(3.5).
