1746-OA8電流元I1dL1對(duì)相距r12的另一電流元I2dL2的作用力df21為:
df21= I1dL1× [(μ0 / 4π)(I2dL2 × r21 / r213)]
式中dL1、dL2的方向都是電流的方向;r21是從I2dL2指向I1dL1的徑矢。
電流元之間的安培力公式可分為兩部分。其一是電流元I2dL2在電流元I1dL1(即上述r21)處產(chǎn)生的磁場(chǎng)為
dB = (μ0 / 4π)(I2dL2 × r21 / r213)

這是畢奧-薩伐爾定律。
其二是電流元I1dL1在磁場(chǎng)dB中受到的作用力df21為:
df = IdL × B
后者即電流元在磁場(chǎng)中的安培力公式。
