An electromagnet is a current-induced magnet. The basic setup is an electrical current circulating around some magnetizable material, such as an iron rod. The current and number of times the current circulates around determine the magnetic strength. Therefore, the same things that strengthen a cu...
the magnetic field becomes much stronger. If the wire is coiled around a central core made up of a material such as iron, the magnetic field grows stronger still -- this is essentially how an electromagnet works
An electromagnet or a superconducting magnet may generate a magnetic field. Furnace and cryostat assemblies are applied to gain variable temperatures—from cryogenic conditions to high temperatures (< 4–1273 K) [325]. A VSM operates on Faraday's law of induction, which states that a changing ...
whereRandLare the effective resistance and inductance of the electromagnet, respectively;Iis the amplitude of the modulation current; andrbis the bit rate (Supplementary Section2shows the derivation). At low temperatures, the resistance of the electromagnet drops and can be made to vanish if the nor...
2. The combination with a camera having a shutter and means operating under pressure to open the shutter and hold it in open position; of a latching mechanism for said shutter opening means and including a latch pin, an electromagnet associated with the said latch pin to release the latching...

CrTe2 thin film below 200 K, a stronger AH resistance appears with a hysteresis loop whose coercivity continually increases as the temperature falls below 100 K. The hysteretic AHE loop indicates that the 1T-CrTe2 thin film exhibits an out-of-plane magnetic easy axis. As we discuss later, ...
only one coil instead of two and its coil is not wrapped around an iron rod like mine. Mine, however, has a stronger electromagnet and runs longer than the Howtoons motor. My motor also has the advantage of two places where the permanent magnet repels/attracts the electromagnet instead of ...
Then, at the desired position of the track 320, the respective electromagnet may be activated. In other examples, the mass 328 may be configured to slide the entire length of the track 320 and then be secured in place. In another example of the protective mechanism 312 of FIG. 6, a ...
8. Lock which can be released on an electrically automated basis as claimed in claim 1, wherein the drive element (16) is provided in the form of an electromagnet (17) with a linearly displaceable armature (19), which is connected via a first articulated link (24) to a first end port...
