WebJan 9, 2024 · When you say Ampere's law, do you mean this: $$ \nabla \times \vec B = \mu_0 \vec J $$ Because that is not the general version of Ampere's law. If you are using Ampere's law without the E-field term (see below), then you are assuming the fields vary slowly in time -- called the 'quasi-static' approximation. If you don't assume slowly varying …
WebSep 12, 2024 · The induced electric field in the coil is constant in magnitude over the cylindrical surface, similar to how Ampere’s law problems with cylinders are solved. Since →E is tangent to the coil, ∮→E ⋅ d→l = ∮Edl = 2πrE. When combined with Equation 13.5.5, this gives. E = ϵ 2πr. mortgage for used mobile homeWebSep 26, 2024 · A solenoid is a long piece of wire which is wound in the shape of a coil.
