A further difference between magnetic and electric forces is that magnetic fields do not net work, since the particle motion is circular and therefore ends up in the same place. We express this mathematically as: W = ∮B ⋅ dr = 0 (21.4.5) (21.4.5) W = ∮ B ⋅ d r = 0.Web

11. You are right: magnetic field lines can't snap or break because they are not physical objects. They are more analogous to elevation lines on a topographical map, or more precisely to lines perpendicular to elevation lines: to the fall lines on a ski slope. However, they do describe something physical, which is the magnetic field distribution.Web

After magnetic separation, the mRNA‐loaded oligo(dT) 25 magnetic particles are first washed with two different wash buffers to remove non‐specific adhering impurities. Before eluting the mRNA, the last wash buffer must be removed and Tris‐HCl buffer is added to the particles. Elution of the mRNA is performed at elevated temperature.Web

Thereafter, the other rotating arm was brought closer and connected to the second magnet's support, which allows safe separation of both magnets. The magnets repelled each other due to their configuration; therefore, the second arm was pushed away by the magnets. The separation of the magnets can be adjusted with extra screws in the …Web
