With 38 days left for NEET UG 2025, candidates must focus on Physics. Understanding the syllabus, practicing numerical problems, and revising key concepts will help improve scores. Smart study ...

Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a ...

The simplest ones are often built in the form of a square or circular sticker ... current through a coil of their own. This generates an alternating magnetic field in the reader’s immediate ...

Contrary to previous assumptions, the Moon's passage through Earth's magnetic field, or "geotail," does not lead to lower plasma densities. Listen to Story Scientists from the Space Physics Laboratory ...

Abstract: Despite passive shielding, eddy current effects due to z-gradient coils in a biplanar permanent magnet low-field magnetic resonance imaging (MRI) system could still introduce artifacts in ...

Abstract: In this article, we present a design for planar coils used in nuclear magnetic resonance gyroscope (NMRG) using genetic algorithm (GA), aiming to provide a highly uniform bias field in ...

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 ...
