A simple needle can turn into a makeshift compass with a leaf & water. 🧭🪡 By magnetizing the sewing pin, you've essentially created a miniature magnet. When this mini-magnet is allowed to float freely on the water, it aligns itself with Earth's larger magnetic field, acting as a compass... show more

In the National High Magnetic Field Laboratory in the U.S. sits "Little Big Coil", the most powerful continuous magnetic field ever created by humans - reaching 48.7 tesla, over 1 million times stronger than Earth's magnetic field. This record-breaking magnet uses a hybrid design, combining superconducting coils with a resistive magnet to push matter into regimes never seen before. Backed by $195M from the NSF and ongoing state funding, NHMFL scientists use it to study quantum materials, extreme superconductivity, fusion-relevant physics, and exotic states of matter. Under fields this intense, atoms distort, electrons behave strangely, and materials reveal secrets that could redefine quantum technology, energy systems, and medical science.

Faraday's Law of Induction ✍️ It describes the phenomenon of how a changing magnetic field around a wire can "force" electricity along its length. As the magnet is moved up and down through the wire coil, the magnetic flux (the number of lines of force) is constantly changing. This constant change leads to an electromotive force (EMF), which behaves like a battery, providing the necessary power for electrons to flow and generate electrical current. The video demonstrates that electricity is not produced simply by placing a magnet near the wire but rather by moving the magnet. The rate at which the magnet is moved dictates how much electricity is created. Nevertheless, as seen from the chart, the movement of electricity ceases completely when the magnet remains stationary, regardless of whether it is inside the coil. Video 📸: py6cj

A neodymium ring magnet on a ferrocell reveals its magnetic field in real time, loops and patterns that expose the surrounding geometry we usually take as learned, here it appears to be innate or inherited.

A rotating magnetic field creates a bound state where two levitated dipole spheres orbit like planets. Their poles stay radial and antiparallel, repelling each other while the rotating magnet stack stabilizes the system, pure magnetic orbital dynamics.

🚨 CHINA JUST ACTIVATED A MAGNET 700,000× STRONGER THAN EARTH’S MAGNETIC FIELD Chinese scientists have powered up a superconducting research magnet reaching 35.6 tesla one of the strongest sustained magnetic fields ever created. For comparison: • Earth’s magnetic field ≈ 0.00005 tesla • Hospital MRI ≈ 1.5–3 tesla • This new system = 35.6 tesla And it can reportedly maintain that field for over 200 hours continuously. Why this matters: Extreme magnetic fields allow scientists to explore matter under conditions almost impossible to reproduce naturally. This could help advance: • superconductors • quantum materials • fusion research • next-generation electronics • exotic states of matter • ultra-precise molecular imaging At these field strengths, materials can begin behaving in completely unexpected ways. Electrons reorganize. Quantum effects dominate. Normal physics starts looking abnormal. The race for stronger magnetic fields is becoming a race to unlock entirely new physics. Humanity is no longer just observing extreme conditions in the universe. We’re beginning to manufacture them on Earth. Follow for more future science and technology breakthroughs.

The majority of people are not even aware that the Earth's magnetic field is weakening, and that everything started around 1850, coinciding with changes connected to the magnetic pole shift. The magnetic field protects us from solar flares, but also from cosmic radiation, especially during periods of Grand Solar Minimum when solar activity is reduced and the sun's magnetic field is weaker. The weakening of the Earth's magnetic field coincides with climate change, but it is not connected to human activity. This climate change causes global cooling. What occurred during the Bronze Age Collapse around 1200 BC is going to happen again in the near future, but it will be even worse. We are about to enter a Grand Solar Minimum, the first since the Little Ice Age, but this time the magnetic field will be much weaker. Do you know that elites are building doomsday bunkers?

We could have a geomagnetic storm today 💥 Earth is being hit by fast solar wind at ~650 km/s with a density <1 p/cm^3. The magnetic field is 10 nT (2x stronger than normal), and the field just flipped into good connection with Earth's (Bz -5 nT).

The Earth's magnetic field protects us not only from solar flares but also from cosmic radiation. When the Sun enters a Grand Solar Minimum, its magnetic field weakens for a long period. This lets more cosmic radiation into the Solar System, and this directly impacts the climate on Earth and increases volcanic activity. The last Little Ice Age occurred during a Grand Solar Minimum. But the coming Grand Solar Minimum is going to hit harder because the Earth's magnetic field is at least 30% weaker and, with the ongoing geomagnetic excursion, is continuing to weaken. This will let in more cosmic radiation, which will directly cause mutations, pandemics, cooling, crop failures, and even crustal displacement. Since the advent of modern technology, we haven't experienced either a Grand Solar Minimum or a geomagnetic excursion, and we are due for both.

On November 27 and 28, a series of powerful solar flares swept across the Sun’s surface, creating this coronal hole. This phenomenon is a temporary region of relatively cool, less dense plasma in the solar corona where the Sun's magnetic field extends into interplanetary space as an open field. The open magnetic field of a coronal hole allows solar wind to escape into space at a much quicker rate, leading to increased chances of geomagnetic storms upon colliding with Earth’s magnetosphere.

🚨 BREAKING Magnetic fields usually destroy superconductivity. But in a new Nature Physics paper, researchers found a 2D crystal where a magnetic field actually helps superconductivity appear. That’s wild. By doping ultrathin LaSb₂ with magnetic Ce impurities, the field suppresses disruptive spin fluctuations allowing a superconducting dome to emerge. So the field isn’t only breaking order. It’s removing the noise that prevents order. That feels like a deeper principle: Sometimes stability appears when the right disturbance cancels the wrong disturbance. Could future superconductors be tuned by controlling magnetic disorder itself? Follow me I track where physics starts breaking its own rules.

“The relevance of this video is showing the repulsion action is all around the rotating magnet and there is also a torque effect which enforces the floating magnet be aligned along the field lines of the rotating magnet.”

If Earth's magnetic field has weakened by more than 10% over the last two centuries, why isn't this the biggest story in the world? It began weakening around the same time that the magnetic poles started shifting and the climate began changing. History always repeats itself. Everything is cyclical.

🚨 BREAKTHROUGH: Physicists just created and directly observed isolated magnetic hopfions using ultrafast laser pulses. That matters because hopfions are not ordinary magnetic textures. They’re 3D topological solitons: closed, twisted spin structures that behave like particle-like knots inside a magnet. Until now, magnetic hopfions had mainly been seen in more complicated linked configurations. This work shows a contact-free way to nucleate isolated ones in FeGe and image them in a transmission electron microscope. The deeper result is even better: The team didn’t just show an image and make a claim. They mapped the nucleation conditions versus laser fluence and external magnetic field, matched the textures against micromagnetic simulations, and derived the relevant topological invariant under realistic boundary conditions. This is why the paper matters: It turns hopfions from a beautiful theoretical object into something that can actually be written, observed, and potentially controlled. That opens the door to 3D spin textures for: • spintronics • neuromorphic devices • topological information storage The real question is: When we can write knotted 3D magnetic states with light alone… does memory stop being about bits and start being about topology? Follow me for more frontier physics.
