Fringing field actuator
WebJul 26, 2024 · It is because the magnetic field lines repel each other when passing through the air (or non-magnetic materials). This effect is known as magnetic fringing. Due to magnetic fringing, the effective area of the air gap is increased and thus the magnetic flux density is decreased in the air gap. WebFigure 5. FEM Simulated fringing field of PP-Cap. and air gap distance can be obtained and they are plotted in 0 0 2 ln 2 lw lw C dd ε π ε π ⋅ ⋅ ≈+. (9) The fringing electric field line and equipotential line can be plotted by solving (3) and (4) as shown in Fig. 3. Depending on how the integration in (7) is approximated
