Ferrite Bar Magnets

Ferrite bar magnets that pick up 20+ uncoated metal paper clips. Certified heavy metal free too! Buy Indigo brand bar magnets where quality+quantity beats "free" shipping.

Ferrite bar magnets blue-red & stamped N-S and magnetized at the ends for repulsion-attraction.

Pick up paper clips or show the shape of magnetic fields with iron filings, compasses or magnaprobes.

  • 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.
