The 16 pages that link to Ampère's circuital law, each with the reason it gives.

• Magnetic fieldRelated: It links circulating magnetic fields to the currents that produce them.

• James Clerk MaxwellRelated: Its original form lacked the changing-electric-field term Maxwell supplied.

• Maxwell's equationsBroader topic: Maxwell's displacement-current term makes this law consistent when fields vary.

• Faraday's law of inductionCompared with: It complements Faraday's law by describing how magnetic fields are generated.

• Magnetic dipoleRelated: It links the currents inside a source to the surrounding magnetic field.

• Biot–Savart lawCompared with: Unlike the magnetostatic Biot–Savart law, it accounts directly for changing electric fields.

• CurlBroader topic: Its differential form uses curl to describe local magnetic-field circulation.

• Stokes' theoremRelated: Stokes' theorem converts its circulation form into a surface integral of curl.

• André-Marie AmpèreBroader topic: It formalizes Ampère’s central link between electric current and magnetic field.

• Hans Christian ØrstedRelated: André-Marie Ampère developed mathematical laws for the magnetic effects Ørsted had observed.

• MagnetostaticsRelated: Symmetry lets it determine fields around steady currents directly.

• Current transformerRelated: It explains how primary current creates the magnetic field that drives the transformer's secondary current.

• ElectrodynamicsRelated: Its original form captured steady currents before Maxwell's extension.

• Displacement currentNarrower topic: Displacement current is the changing-field term that completes this law.

• Displacement current densityCompared with: Its original form omitted changing electric fields, a gap corrected by Maxwell's displacement-current term.

• Toroid (electromagnetism)Related: A circular Amperian path inside an ideal toroid makes its field straightforward to calculate.
