Working Principle of the Superconducting magnet

What is a superconducting magnet?

A superconducting magnet is an electromagnet (coils made of superconducting material) manufactured using superconducting technology and can generate powerful magnetic fields, which have superconductivity and superconducting magnetism at low temperatures.

Applications of Dexinmag Superconducting magnets

The Dexinmag company masters the core technology of superconducting magnets and ultra-low temperature, and has unique technical expertise and rich engineering experience in design and manufacturing; Our products are widely used in many fields such as military industry, medical care, scientific instruments, semiconductors, and large-scale scientific engineering.

Gyrotron superconducting magnet

The gyrotron superconducting magnet is the core component of the electronic rotation resonance system. The products are widely used in radar, electronic confrontation, controlling thermal nuclear polytage, microwave weapons and medical care. In order to ensure the output efficiency of the resonance system, the same axis requirements of the magnetic body are extremely high, and the same axis deviation requires <0.1mm.

Scientific research superconducting magnet

The Dexinmag team has more than 15 years of experience in the thread tube supercorbe magnet. The strength of the standard snail tube magnetic field can be up to 14 T. The split -type superconducting magnet can achieve up to 7T magnetic field strength, which meets various applications such as neutron scattering and spectral experiments. The vector magnet can provide vector magnetic fields tilted or rotated in the two -dimensional or three -dimensional direction, creating more possibilities for strong magnetic field experiments.

Low -temperature strong magnetic system

The low -temperature strong magnetic system can provide a very low temperature (<1.6 k) test environment. The low -temperature system can be matched with a maximum 14T thread tube superconducting magnet or a maximum 9T/1T/1T three -dimensional vector superconducting magnet. Combined with various types of test sample rods and testing systems, it can be achieved in the low -temperature strong magnetic field environment. The material transmission, thermal transportation, the properties of the dielectric, and the magnetoelectric coupling of the material can be achieved.

Superconductivity of Superconducting magnet

When the temperature drops below a certain critical temperature(Tc), the resistivity of the material suddenly drops to zero, for mercury:

Tc=4.2K (-268.9°C)

Superconducting magnetism of Superconducting magnet

The maximal magnetic field achievable in a superconducting magnet is limited by the field at which the winding material ceases to be superconducting, its "critical field", Hc

Hc=Hc(0)[1-T²/T²c]

The working principle of superconducting magnets mainly involves two key effects related to the superconducting state: zero resistance effect and Meissner effect. They are independent of each other.

Superconductivity - zero resistance effect: Zero resistivity ρ=0 (≤10⁻¹⁵Ωm); Conductivity is infinite σ → ∞. When the temperature of a superconducting material is lower than the critical temperature, current can flow inside the superconductor with zero impedance. This is because the electron pairs of the superconducting material combine in the form of Cooper pairs, forming a state called "superfluid".

Superconducting magnetism - Meissner effect: The magnetic induction intensity inside the superconductor is zero B=0.

Meissner effect of Superconducting magnet

1. It has nothing to do with the external magnetic field process. If there is a magnetic field inside the material, the magnetic field will be discharged after entering the superconducting phase; if the object is originally in a superconducting state, the external magnetic field cannot enter the superconductor.

2. The external magnetic field must be less than the critical magnetic field.
