The VBI was originally needed because of the inductive inertia of the magnetic coils which deflect the electron beam vertically in a horizontal blanking interval.
22.
Some experiments ( such as the Madison Symmetric Torus ) use their close fitting shell as a magnetic coil by driving current through the shell itself.
23.
Additionally, U . S . Customs Service agents in the Bahamas detained an American who was acting suspiciously and was found carrying wires and magnetic coils.
24.
Some 258 carloads were shipped under guard by rail to Allis-Chalmers in Milwaukee, Wisconsin, where they were wound onto magnetic coils and sealed into welded casings.
25.
The device has no power supply, rather it contains a millimeter-long magnetic coil that is activated when a scanning device is run across the skin above it.
26.
In 1867 Lord Kelvin patented the syphon recorder, which recorded telegraph signals as a continuous trace on paper using an ink jet nozzle deflected by a magnetic coil.
27.
A rotating magnetic field is produced by external magnetic coils perpendicular to the axis of the machine, and the direction of this field is rotated about the axis.
28.
Through improvements to the magnetic coils of the DC brushless motor, it achieves 30 percent greater assisting and regenerative torque than the previous model without increasing the size.
29.
Other figures of merit of the system are the electric power, mass and volume of the required magnetic field generator ( magnetic coils and / or permanent magnets ).
30.
The other is that the core, where the magnetic coils penetrate the machine along its axis, must be large enough to contain the shielding, which limits the achievable aspect ratio.
