..., and it is the overlapping process that induces current in the coil. When the magnet is at rest in the coil, no current is induced as there is no change in the common field. A second model explains induction based on the idea that a magnet repels or attracts electrical charges: when one pole of a magnet approaches or enters...

.... Multiport Switch Another configuration of the switch is single-pole multi throw (SPNT). When more than one RF component is connected, special care is taken. In Ohmic RF MEMS switches, the switches need to be placed as close as possible to the junction point. In the case of a capacitive switch, switches...

... their drawings with others in their small group and the small groups then present to the whole class. After the whole class discussion, the students revise their drawings to select the “best” model. The text then imposes a two pole representation that uses N and S as the identifiers (rather than + and −). Next...

... the assistant (named Denis Papin) was involved in the design, performance and even documentation of experimental work while receiving no due credit (ibid., p. 559). These cases mark the two poles of a continuum in which Shapin brings up issues such as “moral economy,” class distinctions and tacit...

... attention compared to bulk ME composites in recent times due to (a) the ease of poling (for device application), (b) minimizing the leakage current in turn enhancing the charge storage capacity, and (c) giving leverage to engineer the interface to enhance the strain transfer efficiency. ME coupling...

... sandwiched between two electrodes. In a bimorph, two separate piezoelectric plates are bonded together to form series or parallel generators. When the two layers are polarized in such a way that the voltage across the two layers increases, a series operation is obtained. Alternatively, they might be poled...

... systems to increase the stroke. High piezoelectricity polymers ( Basu et al., 2019a ), deposited thin films, and polymers impregnated with poled piezoelectric ceramic are used. A higher piezoelectric strain coefficient is provided by materials with lower Young's modulus, and hence...

..., the machines have cylindrical (round) rotors, where the excitation winding is wound in slots around the rotor [Fig. 9.1(a) ]. In low-speed generators, such as hydroelectric generators, the machines have salient pole rotors, where the excitation winding is wound around the center core of the rotating part [Fig...

... magnetic field The stator of a three-phase, 3-ϕ, induction motor generates a rotating magnetic field, also termed the rotating magnetic poles, in the airgap (a few millimeters gap) of the machine from a set of three stationary coils. These coils are spread symmetrically in space at 120° apart...
