Question

Ampere's circuital law is especially convenient for directly finding B when sufficient symmetry exists. Which systems have such useful symmetry in their idealized forms?

G1 Physics · Accepted Answer

The first three allow simple Amperian paths on which B has constant magnitude or vanishes on portions. A general finite bent wire lacks that symmetry.
