Charged particles will only experience a force in a magnetic field if they are moving. The direction of the force is both perpendicular ... and the radius of the circular motion can be found. Magnetic ...

Cosmic forensic experts are reconstructing the magnetic field around an infant star from the planet-forming disk of gas and dust around it. How do you dust a star for fingerprints? It's certainly ...

ALMA observations of the protoplanetary disk around HD 142527. The white bars show the directions of the magnetic field revealed by the orientation of the dust grains. The strength of the magnetic ...

New lab experiments reveal that they do a “turtle dance” when they reach an area that they associate with food, indicating how they are using magnetic fields to memorize where ecologically ...

ALMA observations of the protoplanetary disk around HD 142527. The white bars show the directions of the magnetic field revealed by the orientation of the dust grains. The strength of the magnetic ...

are similar stellar remnants that have magnetic fields around 10 to 100 times weaker than "classical" magnetars. Their origins have been a puzzle — until now. The team behind the new research ...

Soft iron is easily magnetized, but unlike some materials (such as steel), it doesn’t remain magnetized once the source of the magnetic field is no longer present. This approach was one of the earlier ...

Electric fields are produced by voltage, and magnetic fields are produced by current. Electric fields and magnetic fields manifest themselves in different ways and have different characteristics. For ...
