Abstract: The magnetic charge model is a powerful tool for calculating the interaction forces between permanent magnets. This model enables the analytical or semi-analytical derivation of mathematical ...

We took the magnet out to Pontiac, Michigan for a full day of exploring. Between the rust, the relics, and a few unexpected surprises, it was definitely worth the trip! Florida property tax to be ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...

The magnetic field that protects our planet is shifting – and one region is fading fast. Over the South Atlantic, a weak spot in Earth’s magnetic shield has grown steadily since 2014. It now stretches ...

The Trump administration is seeking to cool tensions between the U.S. and China, after Beijing unveiled plans to impose export controls on rare-earth magnets and after the U.S. threatened more ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

A study by Alan's Factory Outlet found that birds prefer certain types and colors of vehicles for pooping -- with brown vehicles and Ram trucks topping the list of favorite on-the-fly toilets.

Magnet makers face longer license reviews, sources say Scrutiny is similar to April, at height of U.S.-China trade war China's rare earth exports dropped 31% in September BEIJING, Oct 14 (Reuters) - ...

Inside its boundaries, the magnetic field that radiates away from Earth's interior dips down to an altitude of about 120 miles (200 kilometers) above the planet's surface, which is much lower than the ...

Last week China introduced new draconian restrictions on rare-earth magnet exports, a reminder of its power to disrupt global supply chains—and cause American manufacturers, including carmakers, to ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...
