Why does a magnetic needle show a deflection when brought close to a current carrying conductor?
Because the current carrying coil produces magnetic field around it.
Because electric field of the current carrying conductor exerts force on it
Because of the air between current carrying conductor and magnetic needle.
Because the current carrying coil produces electric field around it.
