A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction of ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

Animals are known to be able to navigate by taking advantage of the Earth’s magnetic fields. But do humans possess the same ability? And do we do so without even knowing? In 2006, an Arizona ...

Magnetic Field Lines: Magnetic field is an important topic in physics, which starts to elaborate at the secondary level. CBSE introduces this topic in Class 10 and then dives into details in further ...

Magnets are defined as substances that can generate a magnetic field. Magnetic fields in modern medicine are widespread due to their physical and chemical properties. As such, there are many uses of ...

Last month, a new superconducting magnet reached its design field of 11.5 Tesla at a temperature nearly as cold as outer space. It is the first successful twin-aperture accelerator magnet made of ...

By using one physical principle—magnetism—to drive both movement and power, the team created a robot that is more efficient, ...

Tokamak Energy’s Demo4 HTS magnet system has replicated fusion power plant magnetic fields at 11.8T, marking a key step toward commercial fusion energy.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...
