We investigate when and why a vector field yields an in-spot spin, also known as curl, and develop intuition to predict the sign of the curl of a vector field without calculating it. As an application of the curl, Stokes' theorem and its physical interpretation are presented with simple ...
The curl formula is derived by crossing the gradient with a vector and finding the determinant of this matrix. What is the curl of a vector field? The curl of a vector field is a measure of how much the vector field swirls. Mathematically, the curl of a vector field is the cross ...
Find the Curl and divergence of the vector field F(x, y, z) = ( xy, -yz2, 2xz2). Find the curl and divergence of the vector field F(x,y,z) = (x+yz) i + (y+xz) j + (z +xy) k Find the curl and divergence of the vector field F(x, y, z) =...
Answer to: Find the divergence and the curl of the vector field F = (y+z) i +(x+z) j + z^2 k By signing up, you'll get thousands of...
2.2.1 Green's Theorem curl-circulation form. For vector field F = Mi+Nj defined on curve c: \int_{c}F\cdot dr = \oint_{c}F\cdot dr = \iint_{D} (\frac{\partial N}{\partial x}-\frac{\partial M}{\partial y})\space dA \oint_{c}F\cdot dr = \iint_{D} (\nabla\...
Well, it means the water is pushing harder on one side than the other, making it twist. The larger the difference, the more forceful the twist and the bigger the curl. Also, a turning paddle wheel indicates that the field is "uneven" and not symmetric; if the field were even, then ...
Now that we have a physical intuition, let’s try to derive the math. In most cases, the source of flux will be described as a vector field: Given a point (x,y,z), there's a formula giving the flux vector at that point.
Example 1: The force on a particle of charge q moving with velocity v in magnetic field B is given by: \boldF=q\boldv×B Suppose an electron passes through a 0.005 T magnetic field at velocity 2×107 m/s. If it passes perpendicularly through the fi...
In three-dimensional Euclidean space, a vector field is said to be irrotational if its curl is zero everywhere and if, in addition, the vector field is smooth, it will be conservative (as Euclidean space is simply connected), that is, it will be equal to the gradient of a smooth ...
