A central primary is flanked by two secondaries, one on either side; the secondary outputs are wired together to form a seriesopposing circuit. AC excitation is applied to the primary, giving rise to inductance currents in the secondaries as mediated by the magnetically conductive core. With the...
In addition to applications in solenoids, relays, and clutches, electromagnets are used to lift heavy masses of magnetic materials. While permanent magnets have a magnetically retentive (hard) coil material, electromagnets have a non-magnetically retentive (soft) coil material that exhibits magnetic pro...
On the right side of the diagram, we see the gate design used in the CELL microprocessor, jointly designed by IBM and SONY. In this pseudo-NMOS design, the two clock phases are non-overlapping, preventing waste due to current flowing through both of the clock transistors, as they are neve...
The reason is that many inductor cores will magnetically saturate if current exceeds the current-rating threshold and flux density becomes too high—resulting in unwanted drastic reduction of inductance.The inductance is formed by wrapping a wire around the core. If there are many turns, the ...

Slight bend in iPad Pro still good remains an issue of concern to many people, although it is understandable that the forces of nature can cause materials to experience wear and tear. Are you one of those with a slightly bent iPad Pro? Fear not, for you are not alone in this predicament...
Whether or not you use the speaker grilles (which attach magnetically, by the way) is up to you, really, because I found that the speakers sound the same with or without them. One thing to consider, however, is that the midrange driver does not have a protective dustcap at its centre...
The ideal solution also would use common materials available from several sources and enable high manufacturability and repeatability on exist- ing production machinery. The challenge is to develop a transformer that operates magnetically on a similar curve to a gapped core yet is not gapped. Our ...
it becomes non-magnetic – and for a similar reason. We can imagine the magnet being made up of many tiny bar magnets, which physicists refer to as magnetic moments. If all these moments are aligned in parallel, the entire material is magnetically ordered and behaves like a magnet. If the...
Leaked iPhone 12 components suggest there's a curious magnet ring inside of the devices, which could be designed to work with these wireless chargers, connecting them magnetically and holding them in place. Other Possibilities AirTags ...
