摘要：
A method of analyzing and calculating magnetic shielding effectiveness of comparators by means of a long rectangular shell model with a magnetic core is developed. A calculation formula is derived. The error between testing results and calculation data for the magnetic shielding effectiveness of a 25 000-A dc comparator is less than 5%. The important design bases for magnetic shielding of comparators are given.
