Two coils that are separated by a distance equal to their radius and that carry equal currents such that their axial fields add are called Helmholtz coils. People in science and industry use coils like this to make regions where the net magnetic fields are relatively uniform (but not perfectly uniform). Let R=0.12 cm, I=22 A, and N=320 turns for each coil. Place one coil in the y-z plane with its center at the origin and the other in a parallel plane at R=0.12 cm. Calculate the resultant field Bx at x1=0.03 cm, x2=0.06 cm, x3=0.08 cm, and x4=0.12 cm. For my answers I got B1 = .00416 T, B2 = .00353 T, B3 = .00306 T, and B4 = .00221 T all of which were wrong. Can you please help me?
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.
