Electric Point Dipole
Electric Point Dipole represents the limiting case of when the length d of a current filament carrying uniform current I approaches zero while maintaining the product between I and d. The dipole moment is a vector entity with the positive direction set by the current flow.
Dipole Specification
Select a Dipole specification — Magnitude and direction or Dipole moment.
Dipole Parameters
Based on the Dipole specification selection:
•
For Magnitude and direction enter coordinates for the Electric current dipole moment direction np and Electric current dipole moment, magnitude p (SI unit: A·m).
•
For Dipole moment enter coordinates for the Electric current dipole moment p (SI unit: A·m).
For 2D and 2D Axisymmetry, the Electric Point Dipole node is only available when the Electric field components solved for is set to Three-component vector and In-plane vector. For 2D, the Out-of-plane wave number should be 0. For 2D Axisymmetry, the Azimuthal mode number should be 0.
In 2D axisymmetry, enter the Electric current dipole moment in the z direction p (SI unit: A·m).
