When the electric field is turned on, the dipole moment ends up aligned parallel to the external electric field.
In electromagnetism, dipoles come in two different varieties. In electromagnetic systems, the separation of positive and negative charges is handled by the electric dipole. A pair of charges of equal magnitude and opposing sign that are typically close together is a straightforward illustration of this system. (An electret is a permanent electric dipole.)
In the current system, a magnetic dipole is a closed circuit. A single wire loop with a constant current is a straightforward illustration. The vector quantity dipole moment can be used to describe an electric or magnetic dipole. The electric dipole moment, which in a basic electric dipole points from a negative charge to a positive charge, has a magnitude equal to the sum of the electric charge intensities times the separation between the charges.
When defining the dipole moment, the "dipole limit" should always be taken into account. For instance, in order to maintain the product, the generated charge spacing should converge toward 0 while the charge strength should diverge toward infinity. (Continuous positive)
