Measurement apparatus, measurement method, and computer-readable recording medium storing measurement program

A measurement method comprising:

• acquiring, by a computer, for each of two samples which are objects made of a same material, have different sizes, and have similar shapes, magnetization curve data measured for the sample and a shape parameter including a dimension of the sample;
• calculating magnetization of an inner part of each of the samples based on the acquired magnetization curve data and shape parameter of the sample by using a model representing magnetization of the object by separating the magnetization of the object into a magnetization component of a surface part and a magnetization component of an inner part of the object in accordance with a volume ratio between the surface part and the inner part of the object;
• and
• outputting the calculated result.

A non-transitory computer-readable recording medium storing a measurement program causing a computer to execute a processing, the processing comprising:

• acquiring, for each of two samples which are objects made of a same material, have different sizes, and have similar shapes, magnetization curve data measured for the sample and a shape parameter including a dimension of the sample;
