For a motor design, you need to design a solenoid coil that produces a magnetic flux density (B) of at least 2000 gauss when a 10 mA current flows through the conductor. Due to space limitations, the coil only can be 10 turns over a 1 cm length. To obtain the needed performance, go to Table 3 and choose a core material for the coil.
