1. A method of measuring properties that relate to an induction heating characteristic of a graphite article, the method comprising:
an arranging step of arranging a graphite article to be able to be electromagnetically engaged with a coil comprising a winded conducting wire; and
a measuring step of applying power for measurement to the coil through a means of measurement connected electronically to the coil, thereby measuring electromagnetic properties induced to the coil,
wherein the coil has a perimeter length of an inner circumference, and
wherein the perimeter length (unit:mm) of the inner circumference and the sectional area (unit:mm2) of conducting wires of the coil have a ratio of 100:1.57 to 161.
