Are Electric Field Lines Parallel?

In uniform electric field, the electric field lines are parallel.

Why are field lines parallel?

When the electric field in homogeneous dielectric between two wide and flat metal plates which are placed in parallel with each other and charged with the same magnitude and opposite signs. Then the electric field lines are parallel to each other.

What do parallel and equidistant field lines represent?

The close continuous curves in a magnetic field are called magnetic lines of force. … Eventually, the strength of the magnetic field is strong where the lines are closer and they weaken as they closeness decreases. Hence, if the field lines in a magnetic field are parallel and equidistant, the magnetic field is uniform.

What happens if magnetic field lines are parallel?

Since the velocity and magnetic field are parallel to each other, there is no orientation of your hand that will result in a force direction. Therefore, the force on this moving charge is zero.

What happens if magnetic field lines are parallel and equidistant?

This statement is false about the magnetic field lines that if magnetic field lines are parallel and equidistant then they represent zero field strength because if they are parallel and are at equal distance then they have uniform magnetic field and doesn’t have zero magnetic field strength.

Do electric field lines make closed loops in space?

Magnetostatic field lines can never form closed loops around empty space. A closed loop of static magnetic field line must enclose a region across which a current is passing. By contrast, electrostatic field lines can never form closed loops, neither in empty space, nor when the loop encloses charges.

What is flux through a surface which is parallel to electric field?

If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero. If the surface is rotated with respect to the electric field, as in the middle panel, then the flux through the surface is between zero and the maximal value.

What are the factors affecting the strength of magnetic field at a point due to a Straightconductor carrying current?

Current and distance from wire

It is clear that the magnetic field at a point due to a straight conductor carrying current is directly proportional the current and inversely proportional to the distance from wire.

Where is the electric field the strongest?

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

Where is the electric field the largest?

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

What are electric field lines?

Definition of Electric Field Lines

An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point.

Are electric field lines straight?

Electric field lines are always straight. All electric potemtials are measured with respect to the negative terminal of the power supply.

What is the formula for electric field?

In vector calculus notation, the electric field is given by the negative of the gradient of the electric potential, E = −grad V. This expression specifies how the electric field is calculated at a given point. Since the field is a vector, it has both a direction and magnitude.

Can electric field lines cross?

Electric field lines cannot cross. If they did, they would be telling you that the force on a charge at that location would point in two different directions, which does not make any sense at all. … If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

How is electric flux calculated?

Know the formula for electric flux.

  1. The Electric Flux through a surface A is equal to the dot product of the electric field and area vectors E and A.
  2. The dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them.

What does electric field depend on?

The strength of the electric field depends on the source charge, not on the test charge. … Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.

What is the angle between electric field and area vector?

If the electric field is uniform, the electric flux passing through a surface of vector area S is ΦE=E⋅S=EScosθ Φ E = E ⋅ S = ES cos ⁡ where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal ( perpendicular ) …

Why can’t two electric field lines cross?

Electric field lines always point in one direction, at any point. When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.

Why electric field inside a conductor is zero?

A conductor is a material that has a large number of free electrons available for the passage of current. … Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

Why are electric field lines discontinuous?

Electric Charges and Fields. … The charge is moving continuously from point to point rather than jumping from one point to another and experiences continuous force in the electrostatic field. The force experienced or the path followed by charge cannot be discontinuous and hence the lines are not broken.

Why are magnetic field lines closed curves?

Magnetic field lines are closed curves as they propagate from the North pole outside the magnet’s body to the magnet’s body and from the south pole to the north pole inside the magnet’s body. Hence, the magnetic field lines are closed.

What is the strength of magnetic field inside a long straight current carrying solenoid?

Answer: The strength of magnetic field inside a long current carrying straight solenoid is the same at all points.

What should be the core of electromagnet?

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail.
