Statement A : The magnetic force on a current element is non-central because the force Bi dl Sin$\theta$ is not function of ‘r’.

Statement B : When a solar flare occurs, large number of electrons and protons are ejected by sun, they enter the earth’s atmosphere, collide with atoms and molecules of atmosphere at poles, it results the beautiful display of colours at poles called Auroraboriolis.

Statement C : Biot-Savart’s law and coulomb’s law both depend inversely on the square of distance but Electric field is produced by scalar source (charge q) and magnetic field is produced by a vector source (i dl).
