The work presents a full-wave investigation of an impedance sphere coated with a rotationally symmetric gyrotropic layer, with both electric and magnetic gyrotropies. A formulation based on the modal ...

The sensor is based on a time-harmonic magnetic field and has the advantage of strong detection ability for nonferromagnetic particles. The sensing mechanism of metal particles is the foundation for ...

It looked still to you before because you were moving with it. We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force ...

Uranus and Neptune, distant blue worlds 1.7 billion miles from Earth, harbor magnetic fields that behave nothing like those of their planetary siblings. While Earth’s magnetic field resembles a bar ...

If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...
