Bio Sawart's Law Vs Columb's Law

Description:

Similarities

• Long range − Both the Biot-Savart’s law and Columb’s law are capable of finding strength of field at longer distance.

• Follow inverse square law − Both the Biot-Savart’s law and Columb’s law are proportionate to 1/r².

• Follow superposition − In Biot-Savart’s law it is allowed to add two magnetic fields at a single point, similarly in Columb’s law it is allowed to add two electric fields at a single point.

Dissimilarities

• Source of electric field E→ is charge q i.e. scalar quantity.

  Source of magnetic field B→ is idl→ which is a vector quantity.

• Electric field E→ acts along r→.

  Magnetic field B→ act normal to r→.

• Electric field E→ is independent of angle.

  Magnetic field B→ depends on angle between dl→ & r→.
