China’s hybrid magnet has just smashed the previous record for the most powerful magnetic field, scientists claim.
At the Chinese Academy of Sciences’ Steedy High Magnetic Field Facility (SHMFF), the magnet years in development has achieved a permanent magnetic field of 45.22 tesla – tens of thousands of times stronger than your average fridge magnet.
This broke the record for a permanent magnetic field of 45 tesla, held by the National High Magnetic Field Laboratory (MagLab) in the United States since 1999. The development sets new limits in conditions that are often used to study various physical phenomena. , offering new research opportunities. and creativity.
Both MagLab and SHMFF research groups have been working on their own hybrid magnets for some time. This is a magnet that uses two different ways to create a magnetic field: a ring on the top of the condom, and an internal resistance bit (that is a magnet based on overlapping plates). Each of these technologies has its own limitations: the superconducting magnet has low power requirements, but the upper limit of the magnetic force; A strong magnet requires a very high power input.
The combination of the two technologies significantly reduces these limitations, allowing the propagation of a strong and continuous magnetic field. This is how MagLab developed its 45 tesla magnet, and how, in 2016, SHMFF achieved a permanent magnetic field strength of 40 tesla – an incredible achievement in itself.
But the team at the Chinese Academy of Sciences were not content to leave it there, and have continued, ever since, to work on their magnet. Finally, your efforts have paid off.
“To achieve [a] high magnetic field, we updated the magnet model and developed a new device,” said physicist Guangli Kuang, academic director of the High Magnetic Field Laboratory at the Hefei Institutes of Physical Sciences, Chinese Academy of Sciences. . “The production process of bitter sauces has also been improved.”
With an installed power of 26.9 megawatts, the team was able to reach their record of 45.22 tesla; and here, too, the magnet seems to be the leader. MagLab’s 45 tesla magnet requires a power input of 30 megawatts.
The SHMFF magnet, the team says, represents a step forward in materials science.
“The integrated magnet of the National High Magnetic Field Experiment Center produces the highest magnetic field in the world, which effectively improves the experimental conditions for scientists to carry out scientific research. scientific research, and will play an important and necessary role in the research of low-power electronics and other fields,” the team wrote on the website of the Advanced Magnetic Field Laboratory.
“As the strength of the magnetic field generated by the hybrid magnet increases, its openness and sharing level and user service level will also be greatly improved.”
Meanwhile, MagLab holds the record for the most powerful magnetic field ever produced on Earth: in 2019, the supermagnet briefly reached a strength of 45.5 tesla in an experiment. We will wait to see if future developments see her officially take the lead.
What explains the age and magnetic patterns of seafloor rocks?
Earth Science Questions – Geology and Tectonics Scientists can determine the age of the ocean floor by examining the changing magnetic field of our planet. Every now and then, the currents in the liquid core, which create the Earth’s magnetic field, reverse: it is called ‘geomagnetic reversal’.
What defines the age of the sea floor? Scientists use the magnetic polarity of the ocean floor to determine its age. Little of the ocean floor is older than 150 million years.

This is because the oldest sea floor is being pushed under other plates and replaced by new ones.
How magnetic patterns develop on the seafloor?
Magnetic stripe patterns develop because, when the oceanic crust splits apart, magma rises to the surface of the mid-ocean ridges and drains to create new groups on the ocean floor.
What is the magnetic pattern of ocean floor rocks?
The scientists found that the honeycomb pattern on the ocean floor was typical of mid-ocean ridges but turned into symmetrical patterns away from the center of the ridge. This normal and inverted pattern continues on the ocean floor. To see also : High-tech seabed mapping finds startling structures everywhere. Magnetometers are still towed behind research ships. They continue to map the ocean floor.
What is the relationship between the age of seafloor and how deep the ocean is?
The depth of the ocean floor on the sides of the mid-ocean ridge is determined largely by the age of the oceanic lithosphere; The old sea floor is deeper. This may interest you : The most realistic sharks in video games. During seafloor spreading, cooling of the lithosphere and mantle, contraction, and age isostatic adjustment cause the deepening of the seafloor.
Why is the ocean deeper than the younger ocean floor? The rate of cooling and lithospheric thickening decreases with increasing distance from the polar axis. At 80 million years old, it reaches its maximum thickness. As it thickens and cools it settles in the asthenosphere. The ocean is deeper on younger ocean floors than on younger floors.
What is the relationship between the age of the seafloor and the spreading centers?
As the rising magma continues, the plates continue to move apart, a process known as sea floor spreading. Samples collected from the sea floor show that the age of the sea crust increases with distance from the spreading center—important evidence in favor of this mechanism.
What is the relationship between the mid-ocean ridges and the age of the ocean floor?
The age, density, and thickness of the oceanic crust increases with distance from the ocean’s edge. Geomagnetic Reversals The magnetism of the mid-ocean poles helped scientists identify the process of sea floor spreading in the early 20th century.
How does Earth’s magnetic field provide evidence for seafloor spreading quizlet?
How does the Earth’s magnetic field provide evidence of sea floor spreading? A. It creates a shifting pattern of rocky ridges on either side of the mid-ocean ridge. A scientist is studying rock formations.
What is the evidence for the flat surface of the ocean floor? What three types of evidence have provided support for the sea floor spreading theory? eruptions of molten material, magnetic stripes in seafloor rock, and the age of the rocks themselves.
How does Earth’s magnetic field provide evidence for seafloor spreading?
When the Earth’s magnetic field reverses, a new line begins, with a new polarity. Such magnetic patterns led to the recognition of the phenomenon of seafloor spreading, and remain some of the strongest evidence for the theory of plate tectonics.
What evidence was used to support magnetic pole reversals quizlet?
Reversals of the Earth’s magnetic field are recorded in iron-rich rocks, such as basalts. The dating of mantle basalts yields time-stored magnetic reversals. measure the bathymetry of the sea floor.
