Field lines aren’t imaginary. A field line is simply a contour along which the field has equal strength. Reconnection is when unconnected contours of the same potential merge and then diverge in a different topology. For reasons we don’t fully understand, but are learning to engineer, this can result in a very powerful acceleration of parts of the plasma medium.
- nabla9 6y agoThat's not true. Magnetic field is a vector field, not scalar field. Magnetic field line is visualization of the direction of the field, not related to the strength. The strength shows in the density of the field lines.
- andrewflnr 6y agoEven if it wasn't a vector, contours of 3d scalar fields are 2d, not 1d.
- simonh 6y agoYou are quite right, my apologies.
