Everyone loves wireless power these days, almost vindicating [Nikola Tesla’s] push for wireless power. One reason why transmitting electricity this way is a terrible idea is the massive losses ...

[James] has a friend who teaches at the local community college. When this friend asked him to build a transformer coupling simulation, he was more than happy to oblige. Fortunately for us, he also ...

Compared to wired, or direct contact, charging methods, inductive chargers are generally less efficient and require larger internal components to operate. In addition, the sensitive inductive coils ...

How efficiently and effectively a workpiece is heated is determined by the design and type of the induction coil. Work coils range in complexity from a simple solenoid- or helical-wound coil (made up ...

Find a downloadable version of this story in pdf format at the end of the story. Use of wireless power involves the magnetic coupling of conductors configured so that the change in current flow ...

In technical terms, inductive coupling is the transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. In an RFID system that uses inductive coupling, ...
