Answer 2

Answer:

Electric dipole and magnetic dipole analogy.

Explanation:

Step 1: Two identical and dissimilar poles that do not exist separately make up a magnetic dipole. In contrast, an electric pole has two equally balanced opposing charges that exist independently.

As the size of the source is decreased to zero while maintaining the magnetic moment constant, a magnetic dipole is the limit of either a closed loop of electric current or a set of poles in electromagnetism. Although the analogy is not exact, it is a magnetic equivalent of the electric dipole.

Step 2: Because it has both charges at the end and is described by the electric dipole moment, an electric dipole is very comparable to a magnet. The sum of the size of the charges and their separation produces the electric dipole moment.

$Magnetism \begin{gathered}\mathbf{m} \\-\mu_0 \mathbf{m} / 4 \pi r^3 \\\mu_0 2 \mathbf{m} / 4 \pi r^3 \\\mathbf{m} \times \mathbf{B}\end{gathered}$
