The relative permeability of 10,000 means that the material can support a magnetic field 10,000 times more dense than than a magnetic field in free space.
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
the plane, or xy plane, has two dimensions space has 3 dimensions
In 2 dimensions, a circle. In 3-dimensions, a sphere.
Spacial dimensions are the dimensions in space such as length,height and depth.
