Magnets

Have you ever tested the strength of a Neodymium Magnet? Well, here is your chance but be careful because some of the larger magnets are very powerful! 

Let's take a look at some of the magnets that we offer:

ALNICO Bar Magnets

    

These bar magnets measure about 1/4" x 1/2" x 3" (72 x 12 x 6 mm). The magnets are made of Aluminum (8%), Nickel (14%), Cobalt (24%), copper (3%) and Iron (51%) which makes for a super strong and high quality magnet.

Alnico bar magnets can be used with iron filings to demonstrate magnetic lines of force. The notched end indicates the North Pole of the magnet. These magnets are ideal for numerous science fair projects or experiments.

Neodymium Ball Magnets

Very Strong N35 Ball Magnet with a diameter of 0.25 inch (about 6 mm).

Neodymium Magnets

A neodymium magnet (a special type of rare-earth magnet) is a powerful magnet made of a combination of neodymium, iron, and boron — Nd2Fe14B. These magnets are very strong in comparison to their mass, but are also mechanically fragile and lose their magnetism at temperatures above 80 degrees Celsius. Neodymium magnets are graded in strength from N24 to the strongest N48.

Neodymium Magnet Uses:

Magnet - Used in various magnet experiments including the Gauss Rifle Kit. 

Toys - Construction toys that use neodymium magnets as building blocks are small in size and stick together strongly. For small children's toys, the magnets are embedded in large, hard-to-swallow plastic parts. The magnets in adult construction kits have a nickel coating. Neodymium magnets also see use as couplers for toy trains and in magnetic puzzles. 

Motors - Electric motors use permanent magnets. The stronger the magnet in a motor, the more power the motor develops. The high strength of neodymium magnets creates small motors with more power than ceramic, iron or other magnet types. Compact neodymium-magnet motors run electric cars, scooters and bicycles. 

Education - Scientific demonstrations benefit from the neodymium magnet's strong magnetic field. The Meissner Effect, a popular demonstration of magnetic levitation with superconducting materials, works best with the strongest possible magnet. Other demonstrations include bending an electron beam in a cathode ray tube with a magnet's field and dropping a magnet down a long aluminum tube to show Lenz's Law. 

Audio - Neodymium magnets have improved the sound quality of portable and desktop music players. Stereo speakers, earphones and ear buds contain tiny magnets that vibrate a diaphragm from an electronic signal, making sound. The strength of neodymium magnets allows small devices to produce high-quality music.
