The invention discloses a proportional electromagnet electromagnetic force horizontal characteristic evaluation method, and belongs to the field of proportional electromagnet performance evaluation and analysis. The method comprises the following steps: firstly, dividing a full working condition plane formed by the working current of an electromagnet and the working stroke of an armature; then obtaining electromagnetic force output by all discrete working condition points through analogue simulation or experimental means; calculating an electromagnetic force average value and a standard deviation of discrete working condition points with equal working current and different working strokes, and obtaining an electromagnetic force overall variation coefficient of the electromagnet according to an algorithm of overall average calculation or weighted average calculation according to working conditions and working areas; and finally, judging the horizontal characteristics of the electromagnetic force of the proport
