| 11. | In this instrument a stationary field coil produces a rotating magnetic field, just like a polyphase motor.
|
| 12. | A polarized-vane synchroscope has a field winding with a phase-shifting network arranged to produce a rotating magnetic field.
|
| 13. | Three similar coils having mutual geometrical angles of 120 degrees create the rotating magnetic field in this case.
|
| 14. | In this instrument, conceptually the field winding produces two rotating magnetic fields due to the running and incoming sources.
|
| 15. | More recently, so-called odd parity rotating magnetic fields have been used to preserve the closed topology of the FRC.
|
| 16. | Three similar coils having mutual geometrical angles of 120 degrees will create the rotating magnetic field in this case.
|
| 17. | The heliospheric current sheet is a ripple in the heliosphere created by the rotating magnetic field of the Sun.
|
| 18. | A rotating magnetic field can be constructed using two orthogonal coils with 90 degrees phase difference in their AC currents.
|
| 19. | This magneto-mechanical attraction creates a force which will drive the rotor to follow the rotating magnetic field in a synchronous manner.
|
| 20. | A rotating magnetic field can be constructed using two orthogonal coils with a 90 degree phase difference in their AC currents.
