MagWeb database groups all magnetic materials into 12 categories, called MagWeb Folders. Each Folder refers to a specific type of steel.  Table 1 lists these 12 MagWeb Folders.

MagWeb Folder thus is a collection of MagWeb files of all magnetic materials belonging to a specific material category.  For example, Electrical Steel (NGO) MagWeb Folder has 409 MagWeb files, each file containing data on specific electrical steel made by a specific manufacturer.  Nickel Steel MagWeb  Folder has 86 different nickel steels made by different manufacturers.   A  MagWeb folder can be downloaded by the user after payment of a nominal fee.

MagWeb File is an Excel file that stores the magnetic property data for a specific magnetic material made by a specific manufacturer.  Each MagWeb file contains either a BH curve, permeability curve or a core loss curve. The MagWeb file that contains BH curve lists several digital points on the curve, as well as the manufacturer, thickness of steel, annealing, Saturation Flux Density etc. The MagWeb file that contains core loss curve lists the core loss data at various frequencies

Product refers to a license granted to a user.  The license grants an unrestricted right to use the MagWeb data that the user downloads through internet (excepting the right for resale.)

We offer 12 MagWeb Folders that are purchasable and automatically downloadable directly from the internet.    By downloading a MagWeb folder, the user agrees to abide by its licensing terms.  The terms of licensing agreement is available in the footer of the home page.
