Permanent Magnet Stabilizing and Calibrating

Permanent Magnet Stabilizing and Calibrating Permanent magnets are utilized in a wide range of commercial and industrial applications, many of which require these magnets to function in a highly stable and consistent manner. Variables such as temperature, and demagnetizing fields will impact performance, but these effects can be mitigated through stabilization or calibration. Our new [...]

Magnetic Putty Magic – The magnetic modeling clay

Magnetic Putty Magic – The magnetic modeling clay “Magnetic Putty Magic“, a strange and fascinating video using the Magnetic Putty, a magnetic modeling clay. This gadget with amazing properties, and a texture between clay and slime, is sensitive to magnetic fields, resulting with some very bizarre behavior in front of magnets… A video directed by [...]

What Are Non-Metallic Magnets?

What Are Non-Metallic Magnets? Non-Metallic Magnets - Scientists have suspected that graphene(a thin, single layer of pure carbon atoms) packed together in a hexagonal lattice structure and thought to be the future of aviation, isthe solution to creating a magnetic material able to hold onto its magnetism up to room temperature. Graphene is already well-known [...]

How does a tool magnetizer and demagnetizer work?

How does a tool magnetizer and demagnetizer work? These things (pictured below). I get how the magnetizer works: a permanent magnet magnetises the tool bit, but how is the magnetic fields arranged in the demagnetizer in order to demagnetize tools? These things are unpowered completely passive blocks, presumaly containing a magnet and some iron/steel parts. [...]

Tiny magnetic sensor deemed attractive

Tiny magnetic sensor deemed attractive, Ultra-sensitive magnetic sensor technology magnetic fields, Sensor Magnet Tiny magnetic sensor deemed attractive - Ultra-sensitive magnetic sensor technology pioneered at PML may soon be commercialized for a host of applications from detection of unexploded bombs and underground pipes to geophysical surveying and perhaps even imaging of the brain and heart. In late October [...]

Optical magnetic field sensor can detect signals from the nervous system

Optical magnetic field sensor can detect signals from the nervous system, tiny magnetic fields, Small magnetic fields sensors, Ultra sensitive magnetic field sensor, sensitive magnetic field sensor The human body is controlled by electrical impulses in, for example, the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various [...]

New microscope technique offers a better way to measure magnetic field of individual atoms

New microscope technique offers a better way to measure magnetic field of individual atoms, IBM magnetic fields A team of researchers at IBM has developed a new way to measure the magnetic field of individual atoms that offers 1000 times the energy resolution of conventional techniques. In their paper published in the journal Nature Nanotechnology, the [...]

Do permanent magnets have a half-life or otherwise “decay” over time?

Do permanent magnets have a half-life or otherwise “decay” over time? from reddit Physics It seems like there must be some energetic cost to constantly exerting a force on the surroundings. As particles & objects resist that force, it must exert some backward torque or whatever on the aligned atoms of the magnet. Over time, [...]

Why buy the New & Improved “Hydro-Soft” magnetic water treatment system?

Hydro-Soft magnetic water treatment system is made with a Epoxy+Nickel+Copper+Nickel quadruple-layer coating, the most effective coating against corrosion. Epoxy+Nickel+Copper+Nickel quadruple-layer coating will last much longer than Nickel coating over time. Nickel coating will corrode over time and cause loss of magnet force. We are the only manufacturer that makes a magnetic water treatment system using [...]

Ferromagnetism

Ferromagnetism, magnetic domains Looking back to the beginning of our thought experiment, magnetic fields may only be produced by a current. Taking the definition of current as a flow of electrons, electrons orbiting an atom should create a current and thus a magnetic field! If every atom has electrons is everything magnetic? YES! All matter, including [...]

Remagnetize a Magnet

Demagnetization is the reduction or elimination of magnetization. One way to do this is to heat the object above its Curie temperature, where thermal fluctuations have enough energy to overcome exchange interactions, the source of ferromagnetic order, and destroy that order. Another way is to pull it out of an electric coil with alternating current [...]

What is a Superconducting Magnet?

A superconducting magnet is an electromagnet where the coils are made of a type II superconductor. It can easily create steady magnetic fields of 100,000 Oersted (8,000,000 amperes per meter). They produce stronger magnetic fields than standard iron-core electromagnets and cost less to operate. Superconductor electromagnets produce a significantly stronger magnetic field than iron-core [...]
