Question

Which distance dependence do the electric field (Coulomb's law) and the magnetic field (Biot–Savart law) share?

पर्याय

• Both follow the inverse-square pattern (1/r²)

• The electric field follows 1/r², while the magnetic field follows 1/r

• Both follow 1/r³

• The electric field follows 1/r, while the magnetic field follows 1/r²

Answer 1

Both laws show inverse-square (1/r²) distance dependence — the same pattern as gravity and electric fields. In both cases, the field weakens rapidly as you move away from the source.
