Abstract:
According to the Biot-Savart law，we derive the magnetic field of the current-carrying tightly wound
bent solenoid with the rectangular cross section，and obtain the analytic solution. Then，by using the Matlab software，the magnetic fields of three typical ring-shaped structures are shown，and the characters of the magnetic field in the semi ring-shaped structure are discussed in more details.
Key words: solenoid, magnetic field, rectangular cross section, ring-shaped, bent
