By Aubree Ross Unlike the geographic North Pole, which remains fixed at 90° latitude, the magnetic north pole is constantly on the move. First identified in 1831 on Canada’s Boothia Peninsula ...
paleomagnetic records show that the intensity drops by up to 90 percent in the process of pole-switching. We should all feel grateful that we live in a time of magnetic stability, because the field ...
Based on the most up-to-date models, the Magnetic North Pole (MNP) is continuing on its trajectory towards Russia. Not to be confused with the Geographic North Pole, sometimes called “True North ...
Let’s get this out of the way—any scientist studying Uranus will tell you that they’re tired of the planet being the butt of ...

Times-Standard on MSNLori Dengler | In praise of maps, good data and concerns for the futureI have always loved maps. My favorite books as a child featured maps. My first forays into backpacking introduced me to ...
Each atom has electrons, particles that carry electric charges,” explains National Geographic ... isn’t absolutely everything in the world magnetic? Well, in a way, it is – but usually ...
Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the ...
He has a master’s degree in civil engineering, with a structural emphasis from Worcester Polytechnic Institute and has more than eight years of experience in transmission line design focused in ...
Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar radiation — and helps guide the migrations of many animals. Loggerhead ...
Our protective magnetic shield stores this energy until there’s too much of it, then boom—the particles zip down the magnetic field lines and into our atmosphere, where they collide with and ...
Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...
