Did you mean "The strength of electric field is positive or negative"?
Anyway, there is your answer..
The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
The electric field is a vector quantity that can have both positive and negative values. The sign indicates the direction of the force that a positive test charge would experience if placed in the field: positive for a repulsive force and negative for an attractive force.
For a positive charge, it points in the outward directios. For a negative, it points towards the charge.

What does a positive mean for electric field strength?
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
The electric field around a negative charge points inward, towards the charge, while the electric field around a positive charge points outward, away from the charge. The electric field strength decreases with distance from both charges, following an inverse square law relationship.
Why similar charges attract each other in physics?
Similar charges, whether positive or negative, create an electric field around them. This electric field exerts a force on other charges within the field. Positive charges repel other positive charges due to the direction of the electric field, while negative charges repel other negative charges. However, positive and negative charges are attracted to each other because their electric fields pull them towards each other.
Electric field lines point in the opposite direction charges would move if they were in the field?
positive
What does a positive electric chrge do?
A positive electric charge creates an electric field around it and interacts with other charges. It repels other positive charges and attracts negative charges. Positive charges move towards areas of lower voltage in an electric field.
A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
Compare and contrast The Electric Field Around The Negative Charge And The Electric Field Around A Positive Charge?
A negative charge is caused by a excess of electrons and a positive charge by their lack.
An electric field begins on north poles and end on south poles?
That is not correct. Electric field lines originate from positive charges and terminate on negative charges. In the case of a uniform electric field, the field lines run from the positive plate to the negative plate.
Why does a dipole moment orient from negative to positive if in an electric field the field runs from positive to negative?
Because opposite charges attract. The negative end of the dipole moment is trying to get to the positive end of the field, and the positive end of the dipole is trying to get to the negative end of the field.
What does a positive mean for electric field strength?
A positive electric field strength indicates that the field is directed away from a positive charge or towards a negative charge. It signifies the direction in which a positive test charge would move if placed in the electric field.
Are positive or negative electric fields dangerous?
No. Any charged object ... the positive and negative ions in table salt, for example... emits an electric field.
When determining an electric field must a positive test charge be used or would a negative one do as well?
Either a positive or a negative test charge can be used to determine an electric field. The direction of the electric field will be defined by the force experienced by the test charge, with the positive test charge moving in the direction of the field and the negative test charge moving opposite to the field.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
The electric field around a negative charge points inward, towards the charge, while the electric field around a positive charge points outward, away from the charge. The electric field strength decreases with distance from both charges, following an inverse square law relationship.

Electric field lines point in the opposite direction charges would move if they were in the field?
positive
How do polar molecules align themselves in a field?
Polar molecules align themselves in a field because they have a positive and negative end. When placed in an electric field, the positive end of the molecule will align towards the negative side of the field, while the negative end will align towards the positive side. This alignment helps to minimize the energy of the system.
What does a positive electric chrge do?
A positive electric charge creates an electric field around it and interacts with other charges. It repels other positive charges and attracts negative charges. Positive charges move towards areas of lower voltage in an electric field.
