Magnetic body analyzing device and magnetic body analyzing method

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a magnetic body analyzing process comprising:

• calculating a change amount by which magnetization vectors arranged on an analysis target change for a predetermined period of time every time the predetermined period of time passes when a magnetic body is analyzed;
• cumulating respective change amounts of the magnetization vectors calculated for each predetermined period of time at the calculating every time the predetermined period of time passes;
• determining whether a cumulated value of the change amounts of the magnetization vectors cumulated at the cumulating exceeds a predetermined change width;
• and
• recording, in a storage unit, the magnetization vectors of a time point at which the cumulated value exceeds the change width when it is determined that the cumulated value exceeds the change width at the determining.

A method for analyzing a magnetic body on a computer, the method comprising:

• calculating a change amount by which magnetization vectors arranged on an analysis target change for a predetermined period of time every time the predetermined period of time passes when a magnetic body is analyzed using a processor;
• cumulating respective change amounts of the magnetization vectors calculated for each predetermined period of time at the calculating every time the predetermined period of time passes using the processor;
• determining whether a cumulated value of the change amounts of the magnetization vectors cumulated at the cumulating exceeds a predetermined change width using the processor;
• and
• recording, in a storage unit, the magnetization vectors of a time point at which the cumulated value exceeds the change width when it is determined that the cumulated value exceeds the change width at the determining using the processor.
