- It can be written as the line integral of the magnetic field surrounding a closed loop equals to the number of times the algebraic sum of currents passing through the loop
- Suppose a conductor carries a current I, then this current flow generates a Magnetic field that surrounds the wire
$(\oint H.dl = {I_{enc}})$
- According to this law, magnetic fields are related to the electric current produced in them
- The law specifies the magnetic field that is associated with a given current or vice-versa, provided that the electric field doesn’t change with time
- It can be applied outside the conductor only
- It is analogous to Gauss law in electrostatics
Gauss law: The total electric flux through any closed surface surrounding charges is equal to the amount of charge enclosed divided by the permittivity.
