The electric lines of forcelines of forceThe imaginary lines which represent the direction of magnetic field, are known as magnetic lines of force. Magnetic lines of force are closed curves. Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole.https://www.toppr.com › ask › question › properties-of-magne…Properties of magnetic lines of force are: – Toppr diverge from positive charge and converge at a negative charge.

What is the electric field of a positive charge?

Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward. When they are represented by lines of force, or field lines, electric fields are depicted as starting on positive charges and terminating on negative charges.

Does electric field diverge from negative charges?

Electric fields diverge from positive charges and converge on negative charges.

Which way does a positive electric field move?

Electric field lines always point away from a positive charge and towards a negative point.

What is the divergence of electric field?

The divergence of the electric field at a point in space is equal to the charge density divided by the permittivity of space.

Why electric field is always from positive to negative?

This is just a convention. The field lines tell us how a positive test charge would move if placed on one of those field lines. Hence the field lines point away from positive charges and towards negative charges.

What does a positive electric field look like?

A positive stationary charge has its electric field lines pointing radially away from it (perpendicular lines away from its surface, in all directions), and a negative stationary charge has its lines pointing radially towards it. Figure 1.

Why electric field is non zero divergence?

The divergence of the electric field is zero except at r = 0. The divergence can be any value if r = 0. From equations (6,9), the volume integral of the diver- gence of the electric field is a random number. By definition, the electric field is in the same direction of the electric force.

Does electric field go from positive to negative voltage?

Electric field lines always extend from a positively charged object to a negatively charged object, from a positively charged object to infinity, or from infinity to a negatively charged object.

Why is the direction of a positive charge in electric field?

Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.

What is the direction of the field line produced by positive charges?

In general, electric field lines are always directed away from positive charges and toward negative charges. Figure 18.23 (a) At any of the eight marked spots around a positive point charge + q, a positive test charge would experience a repulsive force directed radially outward.

Why is electric field outward positive?

We know that charges with the same sign repel each other, So the force on the test charge would be outward (along the line joining them). So the electric field due to positive charge would radially outward. Similar reasoning can be done for a negative charge.

What does it mean if the divergence of a vector field is positive?

If the vector field is increasing in magnitude as you move along the flow of a vector field, then the divergence is positive. If the vector field is decreasing in magnitude as you move along the flow of a vector field, then the divergence is negative.

Do electric field lines diverge from a point?

Electric field lines never diverge from a point in space. 2. A positive point charge in an electric field always travels in the direction of the electric field.

Why is electric field outward positive?

We know that charges with the same sign repel each other, So the force on the test charge would be outward (along the line joining them). So the electric field due to positive charge would radially outward. Similar reasoning can be done for a negative charge.

Is an electric field always positively charged?

Hence, an electric field cannot always be positive.

Where is the electric field zero between positive and negative charge?

There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the “outside” of the smaller magnitude charge.

What is the electric field of two positive charges?

Electric field around two like charges (both positive) In this case the positive test charge is repelled by both charges.

Do electric field lines start or end at positive charge?

The start point of the field lines is at the positive charge and end at the negative charge. For the field lines to either start or end at infinity, a single charge must be used.

Why do electric field lines never cross?

Electric lines of force never intersect each other because at the point of intersection, two tangents can be drawn to the two lines of force. This means two direction of electric field at the point of intersection, which is not possible.

What does a negative electric field mean?

The electric field is a vector and thus has negative and positive directions. If an electron is negatively charged experiences a force against the direction of the field and if an electron is positively charged, it experiences a force along the field.

When the divergence is zero What is the field called?

A field which has zero divergence everywhere is called solenoidal.
