What causes non uniform electric field?

When magnitude and direction of electric intensity are not the same at all the points in the electric field, then it is called a non-uniform electric field.

What happens if the electric field is non uniform?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

What makes an electric field uniform?

A uniform electric field is a field in which the value of the field strength remains the same at all points. In a uniform electric field, as the field strength does not change and the field lines tend to be parallel and equidistant to each other. They are equally spaced.

How do you find non uniform electric field?

For a non-uniform electric field, the electric flux dΦE through a small surface area dS is given by dΦE=E⋅dS d Φ E = E ⋅ d S (the electric field, E, multiplied by the component of area perpendicular to the field).

What is the force in non uniform electric field?

When electric field is not uniform, the net force will be non-zero, there will also be torque on the system. When dipole moment p is parallel or anti-parallel to external field E, the net torque is zero, but there is a force on the dipole E which is not uniform.

Will an electric dipole have translational motion when placed in non uniform electric field give reason for your answer?

Will an electric dipole have translational motion when placed in a non -uniform electric field? … Yes, in a non-uniform electric field, an electric dipole experiences unequal forces at its ends. The two forces,add up to give a resulatant force. Which gives a translatroy motion to the dipole.

Why are the fields around a point charge described as non uniform?

The electric field is generated by a charge q. The larger the charge, the greater the strength of the electric field around the charge. In addition, the further we go from the charge, the weaker the electric field strength becomes. Point charges or charges on spheres produce non-uniform electric fields.

What is uniform and non uniform magnetic field?

We call a magnetic field uniform in a definite area of space if the magnetic field in that space has a stable magnitude and always points in a similar way. Any time the field has varying magnitude or direction, the field is non-uniform.

How you differentiate the breakdown of non uniform fields from uniform fields?

When field is uniform ionization occurs everywhere in the gap due to uniform field intensity and breakdown is observed with spark. In non-uniform field ionization occurs near electrode surface having high field intensity and breakdown occurs with partial discharge and corona. … There is no corona discharge.

What is non uniform charge distribution?

Charge is distributed non-uniformly throughout the volume of the distribution, which has radius of big R, and the charge density was given as a constant ρs times little r over big R, and little r is the location of the point of interest.

What is the flux of a uniform electric field?

Significance The net flux of a uniform electric field through a closed surface is zero.

What is the formula for electric field?

The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q. E has units of N/C. The magnitude of the electric field E created by a point charge Q is E=k|Q|r2 E = k | Q | r 2 , where r is the distance from Q.

What is the difference between uniform and non uniform electric field?

If an electric field has the same magnitude and same direction everywhere in a given space then this electric field is uniform, and if either the magnitude or direction or both change then it is a non-uniform electric field in that specified space.

What happens to a dipole in a non uniform magnetic field?

Assertion: When a magnetic dipole is placed in a non uniform magnetic field, only a torque acts on the dipole. Reason: Force would also acts on dipole if magnetic field were uniform. … In a non uniform magnetic field, both a torque and a net force act on the dipole.
