Magnetic flux generating device

Three-dimensional coil structure: The core of the flux generating device is a set of three-dimensional coils specifically designed to generate the uniform magnetic field required for the experiment. Each dimension has a set of coils that ensure an even distribution of the magnetic field in all three directions.


Power control system: Three corresponding power supplies are matched with the three-dimensional coil, and each power supply is responsible for controlling a dimension of the coil.


High-precision fluxgate probe: In the center of the device, a high-precision inlet fluxgate probe is placed. This probe acts as a feedback test tool for magnetic field regulation and can sense changes in the magnetic field in real time.


Upper computer feedback adjustment: The upper computer receives feedback signals from the fluxgate probe, and adjusts the output current value of the high-precision power supply through calculation and analysis. This feedback adjustment mechanism ensures precise shielding of the geomagnetic field, enabling the generation of the precise magnetic field required for the experiment.

Materials for Magnetic Shielding

 

The best material for magnetic shielding is any ferromagnetic metal. This includes materials that contain iron, nickel, or cobalt.


These materials have high magnetic permeability, meaning they can easily absorb and redirect magnetic fields. When placed in the path of a magnetic field, ferromagnetic shields attract and channel the field lines, effectively reducing the magnetic field strength in the protected area. The thickness and composition of the shield determine its effectiveness.


Most steel types, including our steel discs and plates, are ferromagnetic and serve well for redirecting shields. They are preferred due to their affordability and widespread availability. However, do note that certain stainless steels, particularly those in the 300 series, are not ferromagnetic.


It's also worth noting that our pot magnets are designed with this principle in mind. These specific products incorporate steel to efficiently reduce the field off one side, focusing the magnetic pull in the desired direction. This intelligent design not only optimizes the strength of the neodymium magnet but also offers the versatility needed for varied applications.

FAQ

 

 

Q: How does a high-precision linear power supply affect system performance?

A: It can provide a stable power output to ensure that the system will not affect the stability and accuracy of the magnetic field generation due to power fluctuations when working.

Q: How does the Zero Magnetic Field Shielding System work?

A: The Zero Magnetic Field Shielding System adopts a multi-layer structure, each layer is made of highly magnetic conductive material, which can effectively absorb and disperse the external magnetic field. The multi-layer shield design can further improve the shielding effect, reduce magnetic field leakage, and ensure a zero magnetic field environment inside the system.

Q: How does the coil inside the system achieve precise control of the magnetic field?

A: The coils inside the system control the magnetic field by precisely controlling the magnitude and direction of the current. With a high-precision power supply and control system, fine-tuning of magnetic field strength, direction and uniformity can be achieved.

Q: Is the DXGE-30S equipped with a cooling system?

A: Yes, in order to ensure the proper operation of the equipment and prevent overheating, DXGE-30S equipment is usually equipped with a cooling system. The cooling system can effectively reduce the temperature inside the equipment and maintain the stability and performance of the equipment.

Q: What types of connections do the interface module of the DXGE-30S device support?

A: The interface module of the DXGE-30S device supports multiple types of connections, including USB, RS232, Ethernet, etc. This makes it easy to connect and transmit data to other scientific instruments or computers.

Q: What material is used for the shielding shell of DXGE-30S equipment?

A: The shielding housing of DXGE-30S equipment is usually made of metal materials with high magnetic permeability, such as special alloys or composite materials. These materials can effectively absorb and disperse the interference of the external geomagnetic field, thus ensuring the formation of a stable low-magnetic field environment inside the device.
