When TW flows through the PVC pipe, it … Webincreases the total observed field. This field is frequently called “flux” from the Greek verb meaning to flow. (The symbol for flux is Φ). However, there is no observed flow of matter as there are electrons flowing in an electric current. Figure 4: Normal magnetization curve. The magnitude of the magnetic field per unit area is flux density.
