The basic unit of magnetic pole in the metric system is the Weber or Ampere.meter. Positive and negative electric charge can exist separately. A positive charge is simply the removal of electrons. Magnetic poles can only exist in pairs . An electric field is any region where an electric charge experiences a force.
Electric field is a vector quantity.
The direction of E is the direction of the force on a positive charge. A magnetic field is any region where a magnetic pole experiences a force. Magnetic field is a vector quantity. The direction of B is the direction of the force on a north pole. 2 Electric field lines at any point show the direction of force on a positive charge if placed there.
