Electromagnets
electromagnets - When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet. A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.

Br Magnetic Question
Br Magnetic Question - The magnet I ordered has a Br spec of 12.4 kG - why is the flux density only measuring 3.0 kG? This is best explained through referencing the permanent magnet characteristic of permeance coefficient, which is strictly determined by geometry. In general, longer magnets have greater permeance coefficients. Additionally, a magnet with a higher permeance coefficient functions at a higher operating point. Now, imagine stretching a magnet so that its magnetic length is infinite. Per the previous few sentences, this would result in a magnet with the largest possible permeance coefficient and, consequently, the highest possible operating point. This is the only configuration where a magnet operates at Br.

Neodymium Magnets Falling Slowly Through A Fat-Ass Copper Tube
Neodymium Magnets Falling Slowly Through A Fat-Ass Copper Tube - in Copper, Having A Great Time, How Do They Work?, I Play With Magnets On The Regular So There, Kool, Magnets, Metal, Neato, Physics, Slow, Slow Your Roll Magnet Where You Trying To Go In A Hurry?, Sorcery, That Is A NICE LOOKING PIECE OF PIPE YOU'VE GOT THERE Neodymium Magnets Copper Tube This is a video of a guy demonstrating Lenz's Law with neodymium magnets and a thick-ass copper tube. Why does the magnet fall so slowly? SCIENCE. Via Wikipedia because I suck at explaining things except 1) where babies come from and 2) RPG strategies. Eddy currents (also called Foucault currents) are electric currents induced within conductors by a changing magnetic field in the conductor. These circulating eddies of current have inductance and thus [...]
Why does a spherical magnet fall so slowly through an aluminum tube?
Why does a spherical magnet fall so slowly through an aluminum tube? Charles Platt presents a science demonstration involving magnets that will interest juggalos and non-juggalos alike. magnet aluminum tube To explain the perplexing phenomenon of why a spherical magnet falls so slowly through an aluminum tube, I must refer to the right-handed-corkscrew rule. magnet aluminum tube When I first encountered this rule at the age of 16, I found it very hard to believe. My physics teacher, Mr. Sills, explained it. He was a charming but eccentric vegan who fascinated his students by violating the norms of everyday dress. Because he eschewed all use of leather, he wore tennis shoes, which were mildly scandalous in middle-class British society in 1961. Worse still, because vinyl belts did not yet exist, he held up his trousers with old [...]
Could buckyballs make any metal into a magnet?
Could buckyballs make any metal into a magnet? A layer of carbon can bestow the powers of magnetism. Viviane Richter explains. In a feat of modern day alchemy, scientists have successfully turned non-magnetic metals into magnets. Oscar Cespedes at the University of Leeds and his team published their magnetic recipe in Nature in August. The key ingredient? A dusting of carbon. “This is a new way of making magnets – it opens up a new field!” says Naresh Dalal from Florida State University, who also researches magnetic materials. Magnets are crucial in the age of big data. We’ve generated almost as much data in the past two years as during all of human history. To generate and store it, devices such as smartphones and computer hard drives use tiny, powerful magnets that store data as [...]
Rare Earths
Rare Earth elements, largely unknown to the majority of the general public, have become national news in the past decade. The magnet industry has used samarium, neodymium, dysprosium and other rare earths for decades as they are a very important ingredient in magnet design. Many of these magnets have enabled new technologies and are also critical to green initiatives such as wind turbines and hybrid cars. HSMAG has a “mine to magnet” solution for its production of Neodymium and samarium cobalt magnets. We are the only supplier producing Neodymium and SmCo at three different locations: Lupfig, Switzerland, Rochester, NY and China. Most of the material produced in Lupfig stays in Europe. They also send SmCo block to Rochester, NY for fabrication into magnets for industrial and military use as the material is DFARS compliant. The [...]

The Best Adhesives To Use With Neodymium Magnets
Use With Neodymium Magnets - Frequently for DIY projects and crafts you will need to hold magnets in place using an adhesive. But what type of adhesive works best on neodymium magnets? Most types of strong glue or even strong tape will be effective when attaching magnets to various surfaces. As long as you don’t use hot glue, which uses heat causing magnets to lose their magnetism, you can’t really go wrong with adhesives for magnets. Here are a few types of adhesives crafters can use to secure neodymium magnets in place: Urethane adhesives Super glue like Loctite Liquid Nails Epoxy adhesives Mod podge Silicone adhesives Foam tape The type of glue you use also depends on the material coating the surface of the magnet. For example, many neodymium magnets have nickel coating, which isn’t [...]
Understanding the Milky Way’s Magnetic Field
Understanding the Milky Way's Magnetic Field - You probably already know that our planet has an intrinsic magnetic field, and you might even know that it’s caused by the earth’s swirling molten core. What you might not know, however, is that plenty of other cosmic objects in the universe have magnetic fields, including our very own Milky Way Galaxy. This force, along with gravity, helps hold the galaxy together and is partially responsible for its beautiful spiral shape. Magnetic fields also play a part in astronomical events like solar flares and the evolution of stars. Though scientists have conducted research to better understand these important fields created by our galaxy, they still hold many mysteries.
