The ions are passed into an electromagnet, where they are deflected as a function of the mass–charge (m/z) ratio, their velocity, and the strength of the magnetic field. The electromagnets have their field strength varied to cause variable deflection. The signal strength is recorded as a ...
processing; but, with the advent and applications of neodymium iron boron (NbFeB) permanent magnets in magnetic equipments, the permanent magnet-based magnetic separator has mostly replaced the electromagnet-based one and has become one of the most widely used type in the concentration of magnetic ...
previous detection methods, which leads to a weaker magnetic field induced by the magnetic beads. This can, in turn, reduce the sensor’s sensitivity to the magnetic beads. Second, bead clusters pose a formidable challenge for magnetic biosensors based on the detection of beads. In our ...
The cardiac action potential is a transient reversible electromagnetochemical wavefront responsible for the generation of the cardiac impulse. It is based on a complex series of transmembrane ion fluxes that result in a net flow of electric current across the cell membrane.1,2 First, there is an...
First commercially available preclinical MPI system (Bruker BioSpin MRI GmbH, Germany) deploying an FFP electromagnet topology (up to 2.5 T/m), and a three-axis transmit-receive drive field (~25 kHz and up to ±14 mT/±14 mT/±14 mT) enabling virtually real-time tomographic 3D applications...
If there is no force applied by the piston, the spring pulls the throttle closed. When an actuator input signal energizes the electromagnet in the control solenoid, the pressure control valve is pulled down and changes the actuator cylinder pressure p by providing a path to manifold pressure ...
4. A system for replenishment of energy stored in a battery on an electric vehicle as defined in claim 1, further including electromagnet means (40A, 40B) for releasing a grip on said terminal, energized by a switch operated by release means (50) and lifting plate (13, 14) for pulling ...
An electromagnet is provided to control the timing of the closing lever 33 and comprises an iron core 38 which has two legs for use as magnetic poles. One of the legs is wound with a coil 40 and the core 38 is fixed on the base plate 1 with a setscrew 39. A control lever 41 is...
and hence to produce a relatively large attractive force. The device with such electromagnet is not preferable as it is relatively large in size. Where a smaller electromagnet is used, the spring 4 should provide as small a tensile force as possible. Where the spring 4 is weaker, the locking...
After an elapse of time determined in dependence upon the intensity of the impinging light, the charging voltage of the condenser attains a given voltage and the transistor T1 will be conductive and the transistor T2 will be nonconductive. The electromagnet is thus deenergized and the control lev...
