Neodymium magnets: Standard magnetisation
Practically all our neodymium magnets are magnetised through the width (=height). There are a few exceptions, which are specially noted in the article descriptions.
Diametrical / longitudinal magnetisation of neodymium magnetsA few of our round neodymium magnets are diametrically magnetised:
The following neodymium block magnets are magnetised in longitudinal direction:
Radial magnetisation (ring magnets)
We do not offer radially magnetised ring magnets. It is technically very difficult and also expensive to produce radially magnetised rings. That is why most producers do not offer them.
Often, radially magnetised rings are build with individual radially magnetised ring segments, which we do not carry either. We only offer axially and diametrically magnetised neodymium ring magnets and axially magnetised ferrite ring magnets.
Our ferrite magnets are solely magnetised through the width (=height).
Magnetic tapes and sheets: lamellar
With magnetic tapes and sheets the direction of magnetisation changes every few millimetres, so the north and south poles are laid out in stripes and alternate in close sequence. This leads to an increased adhesive force at direct contact with ferromagnetic surfaces.
The lamellar magnetisation influences how combinable the magnetic tape is. See the following FAQ: How can you combine two self-adhesive magnetic tapes?
