So far, the highest electric field value in a macroscopic system might be a calculated value in magnetars. Magnetars have magnetic fields up to 1011 T, which would correspond, using E=cB, to about 1019 V/m.
Which electrical field is largest?
Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.
What is considered a strong electric field?
ionization chambers. …free electron in a strong electric-field. When the strength of the field is above about 104 volts per centimetre, an electron can gain enough energy between collisions to cause secondary ionization in the gas. After such an ionizing collision, two free electrons exist in place of the original one.
At which point electric field is strongest?
The magnitude of an electric field is directly proportional to the density of electric field lines. When the lines are closer to each other, the >electric field is the strongest; when the filed lines are far apart from each other, the electric field is the weakest.
What is the strongest electric force?
Electrical forces between charges are normally strongest when the charges are close together. … The force between two electrical charges is inversely proportional to square of the distance between them.
What is K in electric field?
The symbol k is a proportionality constant known as the Coulomb’s law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. … The Coulomb’s law equation provides an accurate description of the force between two objects whenever the objects act as point charges.
Can electric field exist without charge?
Yes. The an electric field can exist without a charge. BUT it cannot ORIGINATE without charge. EM waves comprise of electric and magnetic field in transit.
Where is the electric field the strongest and why?
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.
Which is stronger of the two electric field or magnetic field?
The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law. The force created by the electric field is much stronger than the force created by the magnetic field.
Is the electric field real?
The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.
Why do field lines never cross?
So if two lines intersect at any point then two tangents can be drawn at one point indicates two directions ofelectric field, which is not possible because at any point there is only one direction of field. That is why theynever cross each other.
Where is the electric field zero?
For unlike charges, the electric field is zero outside of the smaller magnitude charge. For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges.
Are electric field lines straight?
Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.
What is the weakest thing in the universe?
Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
What are the 5 forces of nature?
The forces controlling the world, and by extension, the visible universe, are gravity, electromagnetism, weak nuclear forces, and strong nuclear forces.
What is the most important force?
Gravity is one of the fundamental forces in the Universe. Although gravity is the weakest of all the forces in the Universe, it is the most important force in the study of astronomy. Originaly defined by Newton, and refined by Einstein, gravity is essentially the natural force of attraction between any two objects.
