Magnetic Effects of Electriuc Current

Ampere’s circuital law

  • The line integral of magnetic field induction B around a closed path in vacuum is equal to m0 times the total current I threading it.
Applications of Ampere's circuital law
  • Magnetic field (B) due to a long straight conductor carrying current is given by B = μ04π2Ir.
        Here, r = radius and I = current
  • It consists of an insu…
