The field is strongest
where the lines are most closely spaced
. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
Where is the electric field strength the greatest?
Electric field strength is greatest
where the lines are closest together and weakest where lines are furthest apart
.
Where is the field strongest?
The magnetic field is strongest at
the poles
, where the field lines are most concentrated.
Where is the electric field strongest between two parallel plates?
Where the field lines are close together the field
is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.
Where is the electric field the strongest in an electric dipole?
The pattern of the lines for the dipole indicates that the electric field is greatest in
the region between and immediately surrounding the two charges
, since the lines are closest together there.
Where is the field strongest weakest How do you know?
Field-Line Patterns
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. If the lines are uniformly-spaced and parallel, the field is uniform.
Why can’t electric field lines cross?
Electric field lines cannot cross. … This is because they are,
by definition, a line of constant potential
. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
Where is a magnet’s force strongest?
Magnetic (like electric forces) act over a distance and is stronger at a closer distance.
Magnetic poles
are the regions where the magnet’s force is strongest, one is the north pole and one is the south pole.
Which magnetic field is the strongest?
The magnetic field of a bar magnet is strongest
at either pole of the magnet
. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
Where is the electric field equal to zero?
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 does the strength of an 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 electric field between two parallel plates?
Two Parallel Plane with Same Charge
Let , we have two parallel infinite plate each positively charged with charge density λ. In the middle of the two plate , both electric fields are opposite to each other . So, the cancel each other and the net electric field inside
is zero
.
What is electric field direction?
Electric field is defined as electric force per unit charge. … The direction of electric field produced by positive charges is
radially outward from the charge
, i.e. away from the point charge. The direction of electric field produced by negative charges is radially toward the charge, i.e. towards the point charge.
What happens when you put a dipole in an electric field?
If a permanent dipole is placed in an external electric field,
it results in a torque that aligns it with the external field
. If a nonpolar atom (or molecule) is placed in an external field, it gains an induced dipole that is aligned with the external field.
What is dipole in electric field?
A pair of electric charges with an equal magnitude but opposite charges separated by a distance d
is known as an electric dipole. The electric dipole moment is a vector having a defined direction from the negative charge to the positive charge. …
What happens when an electric dipole is placed in an electric field?
Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field
is always zero
.
