Controllable magnetic field in the channel. (a)–(d) The magnetic flux density profile in the channel along the x-axis with various values of α. The magnetic flux density at the center of the channel is set to (a) 5, (b) 10, (c) 15, and (d) 20 mT, respectively. (e) The magnetic field in the channel with a magnetic flux density of 20 mT for a parameter change from (i)–(iv) 0.25 to 1.00, respectively (COMSOL Multiphysics 5.4).
