    The 100mm (4″) long ferrite bar magnet can be used for standard physics lab experiments in understanding the nature of magnetic fields;
    Two 100x20x7mm bar magnets were placed in contact with opposing poles (N:N). They were released and the distance caused by the repulsive force was measured.

    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.

    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

    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.

    The ever-popular iconic horseshoe magnet has been used for decades in the classroom and science lab to teach children about physics. These magnets are made from weakly magnetised ferrite material making them ideal for the classroom.

    These pocket-size ferrite U-shaped magnets are weakly magnetised making them perfect for performing classroom experiments and teaching the basics of magnetism. Permanent Ferrite Science School Magnet, Small Ceramic Bar Magnet North South Ploe
