Figure S3 shows the distance traveled by the particles, which was
analyzed based on the maximum x-axis distance reached by receiving the
particle position by analyzing color intensity. When a strike magnetic
field is applied, it can be seen that in Figure S3A, when using the
symmetric BCA, the particles reach the end of the channel, 18mm, but not
in the case of asymmetric BCA shown in Figure S3B. Also, it shows that
the particles move the fastest at 3 Hz and then the speed decreases.
When a rotating magnetic field is applied, the particles reach the end
of the channel faster than when a strike magnetic field is applied. In
detail, it can be seen that the particles move faster in the asymmetric
BCA than in the symmetric BCA. Also, the performance is the best at 8
Hz, and the traveled distance of the particles decreases thereafter.
