The quantum Cheshire cat appears in the weak limit of the interaction. When a sufficiently small magnetic field is applied to path A, there is no impact on the measurement. In contrast, if the magnetic field is applied to path B, the detection rate diminishes, demonstrating that the neutrons magnetism, perpendicular to the plane of the interferometer, predominantly resided in path B. We can do the same with an thin absorber, showing that only the neutrons that are detected are all from path A. This experiment effectively separated the "cat", representing the neutron, from its "grin", symbolizing its magnetic moment out of the plane.
