WebMay 19, 2024 · 对于单层密绕螺线管,它的磁感应强度可以表示为B = μ0 * N * I / L,其中μ0是真空磁导率,N是线圈的总匝数,I是电流,L是线圈的长度。 在这个公式中,N表示线圈的总匝数,而不是单位长度的匝数密度。 因此,单层10000匝和10匝用公式计算磁感应强度B = μ0 * N * I / L得到的结果是不同的。 当线圈的匝数增加时,磁感应强度也会增加。 另 …

WebNov 18, 2024 · A 1.00-m-diameter current loop with 200 turns of wire is adjusted to carry a current of 0.215 A; the coil's field at the center is exactly equal to the earth's field in magnitude but opposite in direction, so that the total field at the center of the coil is zero. What is the strength of the earth's magnetic field at this location? Webb c d 由于 B⊥ad,B⊥bc,所以在 ab 与 bc 两条路径上对 B 积分的结果为 0,所以我们可以得知 b d a B·dl c B·dl 0 从图中我们可以看出,ab=-cd,故 B·ab=B·cd,又因为 ab=cd,所以积分结果为 0。由于 回路选取有任意性,所以管内磁场分布均匀。 rachel ort facebook
