Understanding Magnetic Field Strength
Since 1600 AD, when William Gilbert put his scientific genius into writing De Magnete, creating one of the most admired books in history, many scientists have embraced the field of magnetism as a field of great possibilities. Magnetic fields work on the principle of magnetic materials and electric currents and their effect on other materials with magnetic and electric characteristics. A magnetic field at any given point is specified by both a direction and a magnitude; as such, it is a vector field. Magnetic field strength is the measure of the magnetic field’s intensity.
There are a variety of physical phenomena and simple processes in physics that can show how a magnetic field works. One simple example is a compass. When a compass’s pole is placed near the north pole of a magnet, the needle points away from that direction, and vice versa. This effect is commonly described in magnetic physics as “opposite poles repel, similar poles attract.” A typical physics experiment that you may have done in high school is placing iron filings in a magnetic field. Since iron filings have magnetic characteristics, just imagine how much they would be affected. This experiment visually reveals how the field lines are altered in the process due to the magnetization of the iron filings. Polar auroras, which are streaks of light created in Earth’s magnetic field, also demonstrate the same phenomenon.
When talking about magnetic field strength, you must understand how magnetic flux density works. Since magnetic fields can be visualized as magnetic lines, you can easily determine their strength by observing the density of the lines. This is what constitutes magnetic field strength. The total number of lines emanating from the magnetic field that penetrate a certain area is called magnetic flux, expressed in tesla meters squared or webers (Wb). This magnetic flux density is directly proportional to the electric current measured in amperes and decreases with distance from a current line.
Magnetic field strength is a way to separate the external magnetic influences of different magnetic materials. For example, when placed near magnetic fields, a magnetic material with its own internal magnetic field would interfere with the existing magnetic field lines. Since two sets of magnetic field lines will exist, scientists must find a way to know which field lines come from which material. This is where magnetic field strength, represented by H in the equation B = μ0(H + M), comes in.
The magnetic field has grown into a complex and wide-embracing science, as it has been a focal point in some of the most advanced sciences we have today. Among those using the theories of magnetism and magnetic fields are electric motors, dynamos, Helmholtz coils, magnetic field viewing film, Maxwell coils, Teltron tubes, and stellar magnetic fields. It has also been associated with different mathematical equations and laws, such as Ampère’s law, the Biot-Savart law, magnetic helicity, and Maxwell’s equations.
