Application: School Educations Tool / Kids Toy
Ferrite bar magnet , measures 50mm x 14mm x 10mm. Thicker than most 50mm bar magnet, making it durable . Painted red and blue in 2 halves, with embossed markings of north and south poles respectively.
Use for repulsion-attraction
Will not demagnetize when pushed together
Stamped “N” & “S” & painted red & blue respectively
Paint is guaranteed lead & heavy metal free
Will pick up minimum of 20 uncoated paperclips
Note (1): Ferrite bars are fragile/brittle. Do not drop on hard floors.
Note (2): Ferrite bars are relatively weak & will not magnetize nails or pins. Stronger magnets such as Nd or Alnico are best for this application.
Uses for our Ceramic North-South Bar:
Our Ceramic north-south bar magnets are made of a Ceramic magnet coated in red paint. Each bar is rectangular in shape and is axially magnetized (through length). On each end of the north-south bar is a marked north and south pole allowing easy identification of each pole. Stamped “N” & “S” Painted Red & Nlue Bar Ferrite Magnet
This small magnet makes it possible to identify the poles of a magnet. Use the north-south ends, just place on the magnet and see where it points to! This makes these bars ideal for educational purposes being able to teach about the poles of a magnet. These are available in two different sizes our popular large north-south bar and our small north-south bar. Strontium Ferrite North South Bar Magnets, 75mm Blue & Red Painted Bar Permanent Magnet Ferrite for Kids
Ferrite Magnets are also known as Ceramic Magnets, Ceramic Ferrite Magnets, Feroba Magnets and Hard Ferrite Magnets. Ceramic Ferrite magnets are one of the most widely used permanent magnet materials in the world. Ferrite
magnets are a low cost magnet material perfectly suited for higher volume production runs.
They are termed ceramic due to their excellent electrical insulation ability. Ferrite magnets are superb in damp, wet or marine environments – Ferrite magnets are corrosion free. Because the iron is already in a stable oxidized
form in its structure, the iron cannot oxidize (“rust”) any further when in water.
We usually paint Ferrite educational magnet in no color, red-green or red-blue, or we combine them with other material such as metal and plastic. Meantime, these products comply with the international safety standards.
This pair of bar magnets is polarized on the narrow ends and effective in traditional, simple experiments with magnetism and electro-magnetic induction using coils. Beware of other magnets for sale on the Internet that appear to be a traditional bar, but whose poles are on the long side of the bar and not the narrow ends. 120mm Ferrite Ceramic Magnetic Bar for Experiments
