Magnetic field and gradient calculated for a single micromagnet element (a) Bx, (b) By and the magnetic field gradient (c) and (d)
.
The gray box indicates the positions of the micromagnet. The curves are plotted along horizontal lines (from −40 μm to 40 μm) with different heights (h = 5 μm, 10 μm and 15 μm) on top of the micromagnet.
