Scalar potential and vector potential

A scalar potential is a scalar field whose gradient generates a particular vector field. A vector potential is a vector field whose curl generates a particular vector field.

What is the difference between vector potential and scalar potential?

In vector calculus, a vector potential is a vector field whose curl is a given vector field. This is analogous to a scalar potential, which is a scalar field whose gradient is a given vector field.

What is meant by scalar potential?

In mathematical physics, scalar potential, simply stated, describes the situation where the difference in the potential energies of an object in two different positions depends only on the positions, not upon the path taken by the object in traveling from one position to the other.

What is electromagnetic vector and scalar potential?

An electromagnetic four-potential is a relativistic vector function from which the electromagnetic field can be derived. It combines both an electric scalar potential and a magnetic vector potential into a single four-vector.

How are vector potential and scalar potential related to electric field and magnetic field?

(In the context of electrodynamics, the terms vector potential and scalar potential are used for magnetic vector potential and electric potential, respectively. … For example, since the magnetic field is divergence-free (Gauss's law for magnetism; i.e., ∇ ⋅ B = 0), A always exists that satisfies the above definition.

What is electric vector potential?

The electric vector potential \varvec{\Theta }(\varvec{r}) is a legitimate—but rarely used—tool to calculate the steady electric field in charge-free regions.

Is potential gradient scalar or vector?

We know that potential is a scalar quantity and according to properties of vector and scalar quantity, we know that the gradient of any scalar quantity gives us a vector quantity. Thus we can say that the gradient of potential will be a vector quantity.

Is electric potential scalar or vector?

Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.
