Hard Drives Electromagnets

Hard Drives Electromagnets Hard Drives Although we may not see them every day, hard drives do immensely important behind-the-scenes work. Hard drives store government files, weather reports, your emails, the pictures on your digital camera, and many other things. In fact, hard drives are the backbone of the Internet: almost everything you see online is [...]

Doorbells Electromagnets

Doorbells Electromagnets Doorbells Although almost every house has a doorbell, we rarely stop and think about how they work. At the basic level, a doorbell consists of an electromagnet that triggers some kind of noise (a buzzer, bell, or chime). When you press the button of a doorbell, you are completing the bell's circuit, activating [...]

Maglev Train Electromagnets

Maglev Train Electromagnets Maglev trains (short for magnetic levitation trains) are modern trains that leverage electromagnets. These trains are faster, quieter, smoother, and more efficient than their wheeled counterparts. Maglev trains are common in many Asian and European countries, and are becoming popular in airports as well. Today's fastest Maglev train can speed along at [...]

Speaker Electromagnets

Speaker Electromagnets - Speakers Even if we don't realize it, speakers are all around us. Our TVs, cellphones, headphones, radios, and computers all use speakers of different types. Although there are many different sizes, shapes, prices, and sounds to speakers, they all use the same underlying system, which relies on electricity and magnetism. Speaker [...]

  • electromagnet


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. electromagnet You can make an electromagnet [...]

  • Br Magnetic Question

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]
