\u2192 A magnetic field always associated with a current.<\/p>\n

\u2192 Biot – Savarts law is valid for a symmetrical current distribution.<\/p>\n

\u2192 The magnetic field produced by a circular current carrying conductor is non-uniform but for practical purposes it is considered to be uniform at its centre.<\/p>\n

\u2192 Charges at rest produces electrostatic interaction where as charges in motion produce magnetic interaction.<\/p>\n

\u2192 Magnetic force is much smaller than the electric force.<\/p>\n

\u2192 An oscillating and an accelerated charge produces electro magnetic waves.<\/p>\n

\u2192 The force experienced by a charged particle moving in space where both electric and magnetic fields exist is called Lorentz force.<\/p>\n

\"AP<\/p>\n

\u2192 Ampere’s circuital law states that the line integral of magnetic field (B) around any closed path is equal to \u03bc0<\/sub>\u00a0times the total current (i) in the closed circuit.
