This paper proposes a novel actuation system for simultaneous planar position control of two identical magnetic microrobots. Four rotating permanent magnets are used to produce the desired magnetic field and consequently desired magnetic force. Angles of the permanent magnets are found analytically by PI...
As shown schematically in Fig. 1.51 for a doublet and a triplet, this means that (assuming that the scales of the F2 and J axes are the same) the component peaks of each multiplet will lie on a line making a 45° angle with the F2 axis. If the spectra are rotated counterc...
It is noteworthy that this strategy can be extended to the synthesis of other spinel-type nanosheets, such as manganese ferrites (Supplementary Fig. 3). Figure 1c presents a typical optical microscope (OM) image of ultrathin CFO nanosheets with uniform optical contrast and identical ...
The spring is divided into four equal parts and the same load is suspended from one as these parts. The new time period is……… View Solution Two magnets of magnetic moments M and 2M are placed in a vibration magnetometre, with the identical poles in the same direction . The time perio...
. The endcap and forward regions are instrumented with LAr calorimeters for electromagnetic and hadronic energy measurements up to∣η∣ = 4.9. The muon spectrometer covers the pseudorapidity range∣η∣ < 2.7 and is based on three large air-core toroidal superconducting magnets with ...
1 which has been set to produce a balanced distribution of magnetic fluxes is removed, and it is exchanged for another magnet assembly (11) as shown in FIG. 2 where the intensities of individual magnets of the assembly have been adjusted so as to cause a part of magnetic fluxes emanating ...
a succession of coils facing said succession of magnets, said coils being positioned beside one another along said path of movement in alternating winding senses, each coil being sized so as to be sensitive to a magnetic field of a single magnet when said magnet faces said coil, said successio...
The device forming a homogeneous magnetic field uses two permanent magnets (1,2) spaced apart. Each magnet is shaped as a cone with its frustum cut off, and the bases of the cones face outwards away from each other. Both magnets are the same size. The included angle of the two cones ...
Excitations in magnetic structures of the so-called spin-ice materials generate two different peaks in the specific heat and anomalies in entropy in the temperature interval between 0 and 1 K. These points are due to the existence of two low-energy ex
the repelling and attracting actions thereof develop separately but simultaneously with each other on the common axis and, since the absolute values of the two repelling and attracting forces are identical and cancel each other, the presence of the permanent magnets in no way interferes with the st...
