  1. The Magnetic Fields (named after the André Breton/Philippe Soupault novel Les Champs Magnétiques) are an American band founded and led by Stephin Merritt. Merritt is the group's primary songwriter, producer, and vocalist, as well as frequent multi-instrumentalist.

  2. A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

    Earth's magnetic field is generated by what is known as the geodynamo process. According to National Geographic, for a planet to generate its own magnetic field by the geodynamo process, it must have the following characteristics: 1. The planet rotates fast enough 2. Its interior must have a fluid medium 3. The interior fluid must have the ability ...

    Our protective magnetic "bubble," known as the magnetosphere, protects us from harmful space weathersuch as solar wind. Without the magnetosphere, the solar wind would erode our atmosphere, devoiding our planet of the life-giving air we breathe. According to NASA, the magnetosphere also protects Earth from large quantities of particle radiation emi...

    According to Science Daily, in the last 200 million years alone, Earth's magnetic poles have reversed hundreds of times in a process where north becomes south and south becomes north. The magnetic poles flip approximately every 200,000 to 300,000 yearsaccording to NASA, though it has been more than twice that long since the last reversal. Earth's m...

    Earth is not the only planet in the solar system to possess a magnetic field. Jupiter, Saturn, Uranus and Neptune all exhibit magnetic fields far stronger than Earth's, according to Union University, though the underlying mechanisms driving these magnetic fields are not yet completely understood. Not every planet is fortunate enough to have a prote...

  5. Sep 12, 2022 · Even though there are no such things as isolated magnetic charges, we can still define the attraction and repulsion of magnets as based on a field. In this section, we define the magnetic field, determine its direction based on the right-hand rule, and discuss how to draw magnetic field lines.
