An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. It can reach temperatures that cause the metal to melt [full video:

Ever wondered how a motor can spin without any wires actually touching the moving part?✍️ ε = -N (ΔΦ / Δt) This is a Three-Phase Induction Motor. By using alternating current, it creates a rotating magnetic field that drags the non-magnetic rotor along via electromagnetic induction. Since the aluminum only moves to oppose the changing field, you get high-efficiency, low-friction rotation used in everything from factory tech to EVs. (📽️Credit; physicsisfun_official/Yt )

When a battery's terminals touch steel wool, the electrical current rapidly heats the wire; causing the iron to react with surrounding oxygen, sparking a chain reaction that creates iron oxide, which is heavier than the original wool.

You can use Blender's geometry nodes to solve physics and electromagnetic equations such as Biot-Savart law. You can calculate the magnetic field of a coil anywhere in 3D space and visualise the magnetic fields. Additionally, you can see in real-time how the magnetic field lines change as the coil gets deformed and twisted! #geometrynodes #b3d #blender3d #electronics #Engineering #Science #physics #kicad #circuits

A magnet is an object that creates a magnetic field, which can attract certain metals like iron, nickel, and cobalt. This force comes from the alignment of tiny magnetic fields of atoms inside the material, making it either pull objects toward it or repel other magnets

This setup demonstrates electromagnetic principles . A basic electricity demonstration can be created by wrapping copper wire around iron nails to form coils and placing them near or inside copper pipes. When the coils are moved or connected to a changing magnetic field or an external motion source, a small electrical current can be induced in the wire.

Yes, this is real. This guy decided to flirt with death by putting a light bulb on a fork in a microwave for our entertainment. Here is the fun part. Microwaves hit everything inside with electromagnetic waves at about 2.45 GHz. Normally they make water molecules spin like they are late for work, which heats your food. But an old incandescent bulb has a thin tungsten filament that acts like a tiny antenna. It grabs those waves, turns them into an alternating current, and the filament gets heated to thousands of degrees until it glows like it just found Jesus. The fork adds spice by concentrating the electric field at its prongs. That can create arcs, tiny lightning flashes, and even pockets of plasma inside the microwave. It looks amazing. It is also a great way to shatter glass, start a fire, or send your microwave straight to appliance heaven. So yes, it works. No, do not try this at home unless chaos is your love language.

This is the Meltio Engine, a 3D printer that creates metal parts with high precision. It uses laser-based technology with wire and powder together to build complex parts layer by layer. It is faster than traditional methods and can also repair or upgrade existing metal parts.

Gupta: He keeps citing this constant passing of the Montreal Cognitive Assessment test… This is not a tool that the general public should be utilizing with that level of frequency unless there’s a reason to do it—which is to assess and monitor the evolution of mild dementia or impairment.

Think of it as a Tesla coil for the soul… and for your water This is living water the fourth phase of water structured and activated to supercharge the body with vitality and clarity Copper, when energized with electricity and frequency, generates a force field much like something out of a sci-fi film that emanates outward and interacts with the body. When a frequency such as 174 Hz is applied for pain and inflammation, the magnetic field emitted by the generator pulses through the body at that frequency, supporting relief from pain and inflammation, and promoting balance, rejuvenation, bone density support, and overall vitality.

Black Project Physicist Eric W. Davis says that conventional physics doesn't allow for longitudinal (scalar) electromagnetic waves. Then at the end he says, "there are very specific rare cases of plasmas, and near fields... where there can be a brief longitudinal component of the electromagnetic field." Scalar waves could also be considered gravitational ripples through the Aether. These scientists are very careful in the wording they choose to avoid scrutiny.

NEW: Rep. Tim Burchett tells Tucker Carlson that a high-ranking member of the Navy told him they experienced "something" underwater the size of a football field traveling 200mph. Burchett: "Big as a football field, and that's no fish." Carlson: "So is it possible, given our current understanding of physics, for any man-made machine to go anywhere near 200 miles an hour underwater?" Burchett: "Not with our technology, no."

Polarization of light: It is a property of electromagnetic waves. Electromagnetic waves are three dimensional and polarization is a measure of the spatial orientation of electric field and magnetic field vectors.

Your bed is a frequency. ⚡ You spend 6–9 hours every night immersed in it. The materials matter — they set the vibration of your sleep. 🌌 That’s why you should choose only high-frequency fabrics like linen, silk, or wool… and rest on wood, not plastic or metal. 🌿✨ Sleep is energy. Align it wisely.💫

Clothes are magnetic. 🧲✨ The fabrics you wear interact with your energy field. Ancient civilizations knew this, which is why they chose pure linen robes—a fabric with a high vibrational frequency that supports the body’s natural energy flow. Modern synthetic clothing? It disrupts your frequency. What else have they kept hidden? Learn more: 📕 📘

Dr. Zach Bush reframed the soul in a way that bridges science and mystery: What if your "soul" is the electromagnetic field that reorganizes your entire body every millionth of a second? He explains: You start as one cell that divides like a tumor — until around replication #260, when cells suddenly know exactly what to become (kidney, neuron, etc.) and where to migrate in 3D space. No biological map explains this. The blueprint appears to live in the physics — in the electromagnetic field, the "space between everything." Your body is 99.999% vacuum, yet that vacuum is super-dense with electromagnetic information that keeps manifesting "you" every millionth of a second. You disappear and reappear constantly — and keep coming back as the same coherent self. So perhaps the soul is not something separate that leaves after death… but the organizing field that holds the original blueprint of who you are. Mind-bending or profound? Which part hits hardest — the science of constant re-manifestation, or the idea that "you" are held together by an invisible field?
