Two linear magnet arrays, aluminum rod, mounted six-foot aluminum tube with magnet catcher. Images. Description. This is a commercial device purchased from Pasco Scientific. Two arrays of magnets, containing five strong disc magnets each with small
2013-7-22 As the magnetic array falls, it induces large currents in the aluminum tube. According to Lenz's law, these currents interact with the falling magnet array so as to oppose its (falling) motion, and the array takes several seconds to fall about two meters through the tube. By comparison, the aluminum rod falls much more quickly.

The magnet slows noticably before passing completely through the tube. Electrical current is created in the aluminum tube thereby creating a magnet thereby creating an opposing magnetic flux to slow down the falling magnet.
User Interaction Count: 22014-5-13 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.

2021-5-1 The field-shaper was made of 6061 aluminum alloy, and the steel tube used for welding consisted of # 20 steel tubes and 5052 aluminum tubes, respectively, with a thickness of 1 mm. As electromagnetic forming is a forming technique with a high strain-rate, the constitutive equation should describe the flow properties for high strain-rates.
2021-11-22 As the magnet falls, the magnetic field around it constantly changes position. As the magnet passes through a given portion of the metal tube, this portion of the tube experiences a changing magnetic field, which induces the flow of eddy

The magnet-less trolley is a good baseline, showing what gravity does without any magnetic drag. At these speeds, air drag is minimal and can be ignored. Next, we set a pair of magnets on either side of the aluminum pole, held in place by the 3D-printed trolley. We used 1/2” diameter disc/cylinder magnets for all of these tests.

A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).

2014-2-1 Bi-metal tubes, which combine the advantageous properties of two different metals, are desirable in industries where corrosion resistance is important. A new cladding method named magnetic pulse cladding (MPC) was used to form bi-metal tubes. A cladding of mild steel tube by aluminum alloy (AA3003) was achieved.
2013-2-15 It is a common form of permanent magnet. It is a “hard ferrite” meaning a strong magnet. It is used in things like machines that read magnetic cards, audio speakers, and to smooth out flow in power cables into computers. The list goes on and on. Like the aluminum tubes, it is a question of dimensions taken to prove intent.

Merwin investigated a new magnetic alloy called "alnico" (a combination of aluminum, nickel, cobalt and iron), which possessed exceptional magnetic qualities, including peak magnetic strength up to 30 times that of cobalt steel. He devised a permanent magnetic separator in 1942, sold it to a grain miller and his company was on its way.
