1. Research on superconducting materials:

An important application of strong magnets in ultra-low temperature experiments is to study superconducting materials. Superconducting materials exhibit zero electrical resistance and completely and rapidly repel magnetic fields at extremely low temperatures. The application of a strong magnetic field can significantly lower the critical temperature of superconducting materials, allowing them to achieve superconductivity at higher temperatures. This has important implications for practical applications such as magnetic resonance imaging (MRI) and electrical energy delivery. In addition, by soaking superconducting samples in strong magnets, researchers can deeply study phenomena such as superconducting phase transition, magnetic flux quantum and quantum vortex, which will help to better understand the superconducting mechanism.

2. Quantum Hall effect:

Quantum Hall effect experiments under strong magnetic fields can be used to measure the elementary charge and Haar conductivity of charge carriers. These measurements are important for the study of fundamental physics and also play a key role in the development of resistance standards. By conducting these experiments at ultra-low temperatures, researchers can obtain more accurate and stable results, helping to advance the field of precision measurements.

3. Magnetic material research:

In ultra-low temperature environments, strong magnets can be used to study the magnetic behavior of materials. Magnetic materials may exhibit a variety of different magnetic phases at different temperatures, including ferromagnetism, antiferromagnetism, and spin glasses. By measuring the magnetic response of these materials under strong magnetic fields, researchers can study their phase transition behavior and changes in magnetic properties, which are important for developing new magnetic materials and understanding the fundamental mechanisms of magnetic phenomena.

4. Nuclear magnetic resonance (NMR) research:

Strong magnetic fields are a key component of NMR experiments. In NMR experiments, the sample is placed in a strong magnetic field, and the nuclear spins interact with the magnetic field to produce specific spectral lines. These lines provide information about the molecular structure, chemical environment and kinetics. Superconducting magnets are commonly used to generate magnetic fields strong enough to achieve high-resolution NMR spectroscopy, which has broad applications in chemistry, biochemistry, and materials science research.

5. Magnetic resonance imaging (MRI):

MRI equipment in medicine uses strong magnets to generate a magnetic field, which is used to obtain high-resolution images of the inside of the human body. MRI is a non-invasive diagnostic tool that can be used to detect and diagnose a variety of diseases, including tumors, neurological disorders, and cardiovascular diseases. Strong magnetic fields enable MRI imaging to provide detailed tissue anatomy information, which is critical for medical diagnosis and research.

6. Research on cold atoms and Bose-Einstein condensates:

Strong magnetic fields can be used to refrigerate a gas of atoms, cooling them down to near absolute zero. This cooling technique is used to study quantum phenomena such as cold atoms and Bose-Einstein condensates. These experiments not only help us better understand fundamental quantum physical phenomena, but also have potential applications in quantum information science and precision measurement.

7. High-energy physics experiments:

Large particle accelerator experiments often require strong magnets to bend and focus high-energy particle beams. Strong magnets are used to create particle tracks that allow the particles to interact in particle detectors, allowing the study of the properties and interactions of fundamental particles. These experiments are critical to understanding the fundamental building blocks of the universe and the unsolved mysteries of particle physics.
