Gradient= change in field value divided by the distance
Assume you want to know what is the formula of the gradient of the function in multivariable calculus. Let F be a scalar field function in n-dimension. Then, the gradient of a function is: ∇F = <fx1 , fx2, ... , fxn> In the 3-dimensional Cartesian space: ∇F = <fx, fy, fz>

If you think of it as a hill, then the gradient points toward the top of the hill. With the same analogy, directional derivatives would tell the slope of the ground in a direction.
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.
Gradient= Change in field value/Distance
The gradient of a scalar field represents the direction and magnitude of the steepest increase of the scalar field. It is essential in determining the direction of maximum change in a scalar field, such as temperature or pressure. The gradient points in the direction of the fastest increase of the scalar field at a specific point.

Look up Faraday's Law of Induction. A time-varying magnetic field (i.e. a field gradient) induces an electric field. You could think of this as a transformer, in which the gradient coil is the primary and the human body is the secondary!
Scalar gradient is a mathematical concept representing the rate of change of a scalar field. It measures how much a scalar quantity such as temperature or pressure changes at a specific point in space. The gradient of a scalar field points in the direction of the steepest increase of that scalar quantity.
Gradient ratio is a term used to describe the difference in concentration of a substance between two points in a system, usually in the context of separation processes like chromatography or electrophoresis. It is calculated by dividing the change in concentration by the distance over which the change occurs. A higher gradient ratio indicates a steeper change in concentration over a shorter distance.

In a given region of space, the scalar potential is related to the electric field by the gradient of the scalar potential. The electric field is the negative gradient of the scalar potential. This means that the electric field points in the direction of the steepest decrease in the scalar potential.
The electric field equation describes the strength and direction of the electric field at a point in space. Voltage, on the other hand, is a measure of the electric potential difference between two points in an electric field. The relationship between the electric field equation and voltage is that the electric field is related to the gradient of the voltage. In other words, the electric field is the negative gradient of the voltage.
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.
The electric field and electric potential in a given region of space are related by the equation E -V, where E is the electric field, V is the electric potential, and is the gradient operator. This means that the electric field is the negative gradient of the electric potential. In simpler terms, the electric field points in the direction of the steepest decrease in electric potential.
