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

🚨 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.

The elites know what is coming, and they have known for more than 20 years. According to the leaked 2003 Pentagon report on abrupt climate change, a collapse of the Atlantic ocean current would plunge Europe and North America into sudden cold within a decade, leading to famine, mass migration and wars over food, water and energy. The report compared this scenario to the 8.2-kiloyear event and the Younger Dryas, both periods of abrupt cooling when temperatures dropped within decades. Today, the Atlantic ocean current is at its weakest in over 1,000 years, and scientists warn it could collapse this century. At the same time, Earth's magnetic field has weakened by about 9% since the 1800s, and the magnetic north pole is rapidly shifting toward Siberia. Researchers have linked a collapse of the magnetic field 42,000 years ago to climate chaos across the planet. With the predicted Grand Solar Minimum and the weakening magnetic field, the elites are quietly building doomsday bunkers. Some are building them high in the mountains, while others are constructing them in tropical regions. We know what is coming.

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.

🚨#BREAKING: Watch as lightning strikes a water tower causing it to leak as large amounts of water can be seen gushing out 📌#Stallings | #NorthCarolina Watch this dramatic video capturing the moment a lightning strike hit a water tower in Stallings, Union County, North Carolina, causing a massive cascade of water to pour from the structure. Witnesses nearby described hearing a deafening bang followed by a blinding flash of light. Moments later, they noticed large amounts of water gushing from the top of the tower. At first, some thought the lightning might have struck a fire hydrant, but it soon became clear that the powerful bolt had hit the water tower itself, causing damage. As the impact created a rupture near the top of the tower, leading to a continuous and forceful flow of water spilling down. Emergency crews and repair teams are on the scene, working to control the leakage and assess the extent of the damage. Fortunately, no injuries have been reported

Coffee with mineral water becomes a viral trend The new drink — coffee with mineral water — has quickly gained popularity online, with claims that it boosts energy more effectively than any energy drink. The secret is that the mineral water helps caffeine absorb faster, while also replenishing magnesium and calcium lost due to coffee. The recipe is simple: a glass with ice, mineral water, a shot of espresso, a pinch of salt, and a bit of lime juice.

One old theory suggested that insects were confusing lights with the moon and trying to keep it at a fixed bearing as a compass. We don’t think this is the case as insects would readily swap which side of their body they kept the light on when we switched between 2 lights.
