To use the right hand grip rule, point your thumb in the direction of the electric current, and curl your fingers around the wire; the direction your fingers curl shows the direction of the magnetic ...

If the magnetic field is perpendicular to the velocity, \(\sin(\Theta)=1\) and the force is at a maximum. The direction of the force is found by using the right-hand palm rule: The thumb points in the ...

Electric and magnetic fields are important factors to be considered when designing transmission lines. They occur in nature and have become much more prevalent ... The actual EMF at any point in space ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

At first glimpse, it may seem like infant stars and supermassive black holes have very little in common. Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear ...

Something strange is happening in Earth’s magnetic field, and it has caught NASA’s attention. A massive region of lower magnetic intensity, known as the South Atlantic Anomaly (SAA), has appeared ...

In the middle panel, the color scale of the RM indicates the direction of the magnetic field along the line of sight, i.e., red, away from the observer, and blue, towards the observer.

Watchmakers have devised two different ways to battle magnetism. One is to protect the entire movement with an inner cage made out of a very magnetically permeable material, usually soft iron, that ...

There are a million and one reasons that make Earth habitable for humans and every other creature around us. But central to that is one major thing: the planet's magnetic field. A protective ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.

There is a pretty massive 'dent' in Earth's magnetic field that scientists over at NASA are watching very intently. But just how much of a danger is the phenomenon to humanity and life on the planet?
