Web7 sep. 2024 · A vector field is said to be continuous if its component functions are continuous. Example 16.1.1: Finding a Vector Associated with a Given Point. Let ⇀ F(x, y) = (2y2 + x − 4)ˆi + cos(x)ˆj be a vector field in ℝ2. Note that this is an example of a continuous vector field since both component functions are continuous. Web10 apr. 2024 · Probably none, except the Maxwell equation itself. The equation ∇ ⋅ B = 0 restricts the set of possible magnetic fields, because the right-hand side is constant in time and there is no other variable in the equation than B. This kind of equation is sometimes called a constraint equation. The equation ∇ × B = μ 0 j + ϵ 0 μ 0 ∂ E ∂ t,
WebThe equation for A is a vector equation. In Cartesian coordinates, the equation separates into three scalar equations: [6] In this form it is easy to see that the component of A in a given direction depends only on the components of J that are in the same direction.
