    The magnetic field is the area around a magnet in which there is magnetic force. moving electric charges can make magnetic fields. magnetic fields can illustrated by magnetic flux lines. at all times the direction of the magnetic field is shown by the direction of the magnetic flux lines. the strength of a magnet has to do with the spaces between the magnetic flux lines.

  • The earths magnetic field just did something scientists

    The research group led by ryan mcbride, an associate professor of nuclear engineering and radiological sciences at u-m, tests ways to achieve states like this by imploding plasma cylinders with magnetic fields. these cylinders have a tendency to break up in a sausage link fashion when the magnetic field finds tiny divots in the cylinders surface and cuts into them. the technical term is sausage instability.

    The butter in mcbrides analogy is plasma and the fingers are magnetic field lines. his group looked for a way to keep the magnetic field from digging into the imperfections in the cylinder, instead causing the field to press more uniformly on the cylinders outer surface. they did this by twisting the magnetic field into a helix, that spring-like shape, and varying the angle at which the helix pressed on the plasma cylinder. this made it harder for the magnetic field to slice inthe field moved across many divots rather than pressing into any one divot for too long.
