For those of you who are into this kind of thing - here's my LOGIC to justify the magnetic dipole. Let me know if there's an error. I'm using a variation of this for our second paper.
Faraday proposed that magnetic fields are structured along lines of force. The voltage across a magnet or an induced magnetic field has two distinct poles or charges. Therefore lines of force also have two distinct charges. This field condition can be sustained if there is a further proposal made that the lines of force comprise magnetic dipoles, as this would satisfy the required 180-degree alignment of those lines of force. Current is widely ascribed to the movement of charge and it is known to induce electromotive force on circuit material. Electromotive force is measured as potential difference or voltage. And voltage, in turn, is a measure of an imbalance where the negative and positive charges are separated at the terminals of a supply source or across circuit components including the wire. This negative and positive charge imbalance is reduced, proportional to the rate of current flow. As electromotive force is known to be proportional to the rate of change of magnetic flux, and as current flow is proportional to the rate of change of the electromotive force then it may be proposed that both voltage and current flow may have this material magnetic property. Therefore, both current and voltage can, in turn, be modeled along Faraday’s lines of force. Current flow would then vary the distribution of that material throughout a circuit, which would then result in a redistribution of charge. In effect, a magnetic field in a condition of voltage imbalance, would be in a dynamic condition to redistribute that charge provided it is able to generate current flow through circuit material in order to enable that redistribution
