WebAug 3, 2024 · Once the lava cools to about 1,300 degrees Fahrenheit (700 degrees Celsius), the strength and direction of the magnetic field at that time become “frozen” into the rock. By sampling and radiometrically dating the rock, this record of the magnetic field can be revealed. Studies of Earth’s magnetic field have revealed much of its history. WebIf field strength increases in the direction of motion, the field will exert a force to slow the charges, forming a kind of magnetic mirror, as shown below. When a charged particle moves along a magnetic field line into a region where the field becomes stronger, the particle experiences a force that reduces the component of velocity parallel to ...
