PURPOSE:To obtain high uniform magnetic-field distribution by symmetrically arranging first and second coil groups, holding a plane in space, mounting first-fourth saddle-shaped coils to each coil group and forming these coils under specific conditions. CONSTITUTION:First and second coil groups 1, 2...

The system is based on a nulling field coil fed by a current on the basis of the residual field, sensed by a magnetic sensor (Hall or magnetoresistive) placed in the coil center. In this way, the coil current proportionally represents the external field component along the coil axis, and...

Magnetic field caused by current in a wire. This field is identical to the field surrounding a permanent magnet. In fact, if you coil the wire like what's shown in Figure 2.40, the magnetic field lines align and reinforce each other, making it even more like a permanent magnet.33 Sign ...
Figure 3.A schematic diagram of gradient orientation, strength, and polarity. Thezaxis is parallel to the bore of the magnet. Arrows indicate the strength of the magnetic field (B0). Figure 4shows an example of a gradient diagram used to show the time sequence of gradient applications. ...
The setup schematics and the sample’s design were optimal to be measured in TMOKE geometry according two reasons: (i) the magnetic field was applied in-plane along the easy magnetization axis, and gave the highest ratio of the magnetic moment modulation in fields with magnitude below 50 Oe36...
A method for monitoring the misalignment of the magnetic axis in solenoids is proposed. This method requires only a few measurements of the magnetic field at fixed positions inside the magnet aperture, and thus overcomes the main drawback of sturdy moving mechanics of other Hall sensor-based metho...
A difficult problem concerns the determination of magnetic field components within an experimentally inaccessible region when direct field measurements are not feasible. In this paper, we propose a new method of accessing magnetic field components using
magnetic field by providing a first segment out of both segments that can subordinate to the respective turns and are extended in the circumferential direction on a small radius to the utmost with regard to the cylindrical axis, and by providing a second segment on a large radius to the ...
