Any field pure can be interpreted as a constant differential field.

Suppose we have a material in its normal state, containing a constant internal magnetic field.

The conservation law can be used to express the speed of a body in a constant gravitational field as:

Maxwell coil - a device for producing a large volume of an almost constant magnetic field.

The constant field and the pulse field are usually set perpendicular to each other.

The electromagnet is positioned in a constant magnetic field created by a permanent magnet.

Let us consider now a somewhat different example where instead of uniform translation the loop rotates in a constant magnetic field.

The coating can be on the inside of the tube, where it helps to maintain a constant electrical field near the screen.

We then put this object in a constant magnetic field:

Now consider a segment of a conductor displaced in a constant magnetic field.
