Write the analogy between electrostatics and magnetism.
The analogy between electrostatics and magnetism is summarized in the table below:
| Physical quantity | Electrostatics | Magnetism |
|---|---|---|
| $(1)$ Field | Electric field $\overrightarrow{E}$ | Magnetic field $\overrightarrow{B}$ |
| $(2)$ Source | Charge $(q)$ | Magnetic pole strength $(q_m)$ |
| $(3)$ Dipole moment | $p = q(2a)$ | $m = q_m(2l)$ |
| $(4)$ Constant | $\frac{1}{4\pi\epsilon_0}$ | $\frac{\mu_0}{4\pi}$ |
| $(5)$ Length of dipole | $2a$ | $2l$ |
| $(6)$ Direction of dipole moment | From negative to positive charge | From South to North pole |
