When I first met the little donut antenna, I sensed it was hiding a secret - no this time not the two coils connected in anti ...

This magnetic induction technology quietly opens possibilities for communication in extreme environments, where traditional ...

Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...

Exploring power output in a magnetic loop using Faraday’s law and understanding how changing magnetic fields generate electrical energy. Learn the fundamental principles of electromagnetic induction, ...

Explore two effective methods for finding the magnetic field of a current-carrying wire loop. This short explains the reasoning behind each approach and shows how they connect theory with practical ...

The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into a small space. It takes the form of a large single-turn coil made into a ...

Five members of the Cornell Hyperloop project team competed at the 2025 Hyperloop Global Conference, hosted at Queen’s University in Ontario, Canada, this past summer. Among top international teams, ...

Leaker Majin Bu reports that Apple is developing a new iPhone 17 accessory: a shoulder strap for cases where the iPhone 17 hangs over your hip like a small bag. It keeps the iPhone always at hand, and ...

Abstract: We present a method for designing a novel broadside radiated loop antenna utilizing the tapped-feeding method. The tapped feeding along the magnetic wall of the loop is employed to perform ...

Abstract: This letter develops an on-glass omnidirectional loop antenna using electrically small open-end subloops to achieve a dominant magnetic dipole moment. The open-end loop geometry facilitates ...
