Electric Field Direction At The Center Of a Dipole?

  • #1
Ok we know for a Dipole the direction of Electric Field for points on the the dipole axis is in the direction of Dipole Moment(from -ve to +ve charge) rite? Now we also know that fields emanate from +ve charge and extend towards -ve charge. So what will be the direction of Electric Field at the center of Dipole? In the direction of Dipole Moment(ie. from -ve to +ve) or from +ve charge to -ve charge(electric fields originate from the +ve charge and extends towards -ve charge rite?):confused:
Please clear my misconception?

Opposite of the dipole moment. Your first sentence is valid for magnetic dipoles, and this is the fundamental difference between the two.

Fundamental difference between two??
Magnetic dipole? What other kinds of dipoles are there?
So you mean for a magnetic dipole the direction of electric field at the center is in the direction of dipole moment?
Please be clear.

For a magnetic dipole, the direction of the magnetic field is the same as the direction of the magnetic dipole moment at the center of the dipole.

For electric dipoles, the direction of the electric field, being always from the positive to the negative charge, is directed oppositely from the direction of the electric dipole moment at its center, being conventionally chosen to be from the negative to the positive charge.

Got it :)
Thanks
