The manufacturer of Square Helmholtz Coil tells you that if there are a pair of identical current-carrying circular coils that are parallel to each other and coaxial, and the current is passed in the same direction, when the distance between the coils is equal to the coil radius, the total magnetic field of the two current-carrying coils is near the midpoint of the axis. It is uniform over a large range. Therefore, it has great practical value in production and scientific research, and is often used in the measurement standard of weak magnetic fields.

The characteristics of magnetic field distribution are: Square Helmholtz Coil manufacturers tell you that a magnetic field with high uniformity is generated internally. Generally, the uniformity of long solenoids is better than that of Helmhol coils, but compensation coils can be added to both to obtain high uniformity. uniformity.
The manufacturer of Square Helmholtz Coil tells you that due to the open nature of Helmholtz coils, other instruments can be easily inserted or removed, and visual observation can also be made directly. Therefore, it is a commonly used device in physical experiments. Named after German physicist Hermann von Helmholtz.
The Square Helmholtz Coil manufacturer tells you that the power frequency magnetic field is characterized by low frequency and long wavelength, and its test waveform is a power frequency sine wave, which can affect various electrical and electronic equipment to varying degrees. For example, a type of equipment such as an watt-hour meter may cause malfunctions such as program disorder, memory data loss, and metering errors under the action of power frequency magnetic fields.
