Biot-Savart law in magnetism is analogous to Coulomb’s law in electricity. According to Biot Savart law, magnetic flux density
\\(\\begin{array}{l}H=\\frac{\\mu _{0}I.dl\\;sin\ heta }{4\\pi r^{2}}\\end{array} \\)
which is analogous to the electric field
\\(\\begin{array}{l}F=\\frac{q_{1}q_{2}}{4\\pi\\epsilon _{0} r^{2}}\\end{array} \\)
which is Coulomb’s law.
