Two 75x18x6.5mm bar magnets were placed in contact with opposing poles (N:N). They were released & the distance caused by the repulsive force was measured.
This 75mm blue & red painted bar magnet is ideal for doing magnetic repulsion & attraction experiments;
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 100mm
