It is the rate of change in the vector for a unit change in the direction under consideration. It may be calculated as the derivative of the vector in the relevant direction.
Vector.
Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
Charge is not a vector.
Gradient= change in field value divided by the distance
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
The gradient dot product is a key concept in vector calculus. It involves taking the dot product of the gradient operator with a vector field. This operation helps in understanding the rate of change of a scalar field in a given direction. In vector calculus, the gradient dot product is used to calculate directional derivatives and study the behavior of vector fields in three-dimensional space.
it used in our practical life.. for ex. in hills r in mountains
In the name of God; It must be mentioned that a vector has two important characteristics; 1- direction and 2- quantity. in other word for identification a vector these two characteristics must be defined. for example when we speak about displacement of a body it must has direction and quantity. but about gradient, it has a general mean: difference. Also a specified mean may be defined for it: "any increase or decrease in a vector or scalar field". it is a vector field.
An example of the divergence of a tensor in mathematical analysis is the calculation of the divergence of a vector field in three-dimensional space using the dot product of the gradient operator and the vector field. This operation measures how much the vector field spreads out or converges at a given point in space.
Temperature gradient is a vector quantity. It represents the rate of change in temperature with respect to position and has both magnitude and direction.
The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.
No, the Laplacian is not a vector. It is a scalar operator used in mathematics and physics to describe the divergence of a gradient.
It stands for gradient vector flow.
No, the curl of a vector field is a vector field itself and is not required to be perpendicular to every vector field f. The curl is related to the local rotation of the vector field, not its orthogonality to other vector fields.
The curl of an electric field is zero because electric fields are conservative, meaning the work done by the field on a charge moving around a closed path is zero. This implies that the circulation of the electric field around any closed loop is zero, leading to a curl of zero.
The equation that connects the scalar potential (V) and the vector potential (A) is given by: E = -∇V - ∂A/∂t, where E is the electric field, ∇ is the gradient operator, and ∂t represents the partial derivative with respect to time.
Gradient= Change in field value/Distance
