Therotor and statorconfiguration of an iron-core PM dc motor is shown in Figure 5.2.2. 铁芯永磁直流电动机的转子和定子结构如图5.2.2所示。 The permanent-magnet material can be barium-ferrite, Alnico, orrare-earth compound. Themagnetic fluxproduced by the magnet passes through aliminated rotor s...
Figure 3 shows that in a presence of a guide field, strong ion and electron spectra (see Methods) are also recorded being ejected along the current sheet axis (the z-axis), i.e., along the expected outflow direction (as indicated in Fig. 1). Quite differently, no signal in both chan...
Figure 1 (a) The XRD spectrum of Co–Zr–Ta–B films deposited under different argon sputtering pressures (1.6–6.2 mTorr). (b) SAED pattern of the film deposited under 6.2 mTorr argon pressure. Full size image The resistivity (ρ) of each film was measured using a 4-point probe in...

A two-dimensional pulsatile flow of MP fluid was analyzed by a uniform magnetic field applied perpendicular to the flow direction, as shown in Figure 1. The geometry under consideration was a constricted channel. The center of the constriction was placed at 𝑥=0 with a total width of constri...
If we consider the movement of a single tracer particle in a saturated porous medium under a constant piezometric head gradient in the x direction, we can understand the phenomenon clearly (Figure 1.1). In the absence of a porous medium, the particle will travel in the direction of the ...
V 2 = N V 1 and I 2 = I 1 / N, where N is the turns ratio. Since Z 2 = V 2 / I 2 and Z 1 = V 1 / I 1 , Z 2 = N 2 Z 1 . That is, the impedance ratio is the square of the turns ratio. Figure 1a Autotransformer ...
Each snapshot is taken at the time shown in the figure. In the left column, dotted lines indicate the radius [Math Processing Error] and the longitude [Math Processing Error]. Fig. 4 shows time-azimuthal sections of [Math Processing Error] at [Math Processing Error] for runs 4R5, 5R5,...
1(f). For a majority of the measurements, the magnetic field is first applied in-plane with the film and perpendicular to the current direction, as indicated in the figure. The magnet is then incrementally rotated around the sample in the cryostat using the rotating platform such that the ...
