  6. Magnetic field - Wikipedia

    • The direction of magnetic field lines represented by the alignment of iron filings sprinkled on paper placed above a bar magnet.
    • In a modified form that accounts for time varying electric fields, Ampère's law is one of four Maxwell's equations that describe electricity and magnetism.


  7. Interaction of Magnetic Dipoles in External Fields

    • Here i is the current in the loop, A is the loop area, R is the radial distance from the center of the loop, and θ is the polar angle from the Z-axis. The field is equivalent to that from a tiny bar magnet (a magnetic dipole).
