Electromagnetic field[edit | edit source]

When connect electric conductor with a voltage source , the current flows through conductor creates magnetic field different shapes for different arrangements . Field of Electromaget lines running from north pole to south pole include

Intensity of electromagnetic field[edit | edit source]

The strength of magnetic field can be calculated by Ampere's law
