Differential electromagnets are used to measure the difference in magnetic fields between two points. Differential electromagnets are typically used in measuring instruments. The most common application is in a galvanometer, which measures the difference in current between two points.

Differential electromagnets can also be used to measure the difference in magnetic fields between two different metals. For instance, they can be used to measure the difference in magnetism between two different types of steel. This can be useful in determining the magnetic properties of certain metals, such as which type of steel has the highest magnetic permeability.

Differential electromagnets can also be used to detect changes in magnetic fields. A typical application of this is in medical diagnostics, where doctors use a device called a magnetoencephalography (MEG) to detect changes in the magnetic fields generated by the brain.

In addition to their uses in medical diagnostics, differential electromagnets can also be used to detect changes in the earth's magnetic field. This information can be used to predict changes in the weather, as well as to help scientists better understand how the earth's magnetic field works.

Differential electromagnets can also be used to build high-precision instruments, such as precision scales, to measure very small changes in the strength of magnetic fields. Such instruments are often used in scientific research, where accuracy and precision are critical.

Overall, differential electromagnets are incredibly useful tools that can be used in a variety of applications. They are most commonly used to measure the difference in magnetic fields between two points, but they can also be used to detect changes in magnetic fields or to build high-precision instruments.
