| Weak nuclear force | 10–13 | Very short, Sub-nuclearsize (-10-16m) |
| Electromagnetic force | 10–2 | Infinite |

How strong is the electromagnetic force?
“Is the electromagnetic force really strong?” It is very strong and this is surprising too because it can work over an infinite range. To give you an idea, the electromagnetic force is approximately 1036 times stronger than the earth’s gravitational field!
Does electromagnetic force have infinite range?
In contrast to the nuclear forces, both the electromagnetic force and gravity have effectively infinite range* and die off in strength as 1/r2.
Which is the longest range of force?
Longest range force is gravitational force and nuclear force is shortest range force.
What is electromagnetic force?
The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It acts between charged particles and is the combination of all magnetic and electrical forces. The electromagnetic force can be attractive or repulsive.
Is electromagnetic force stronger than gravity?
Electromagnetism – the force we know best – is 10 to the 36th power stronger than Gravity. That’s 10,000,000,000,000,000,000,000,000,000,000,000,000 times stronger! The “strong” nuclear force is 10 to the 38th power stronger than Gravity.
What is the range and relative strength of electromagnetic force?
4 Fundamental Forces Force Relative Strength Range Strong 1 ≈1 fm Electromagnetic 10 Infinite (∝1/r2) Weak 10 ≈10–3 fm G. Page 1. 4 Fundamental Forces. Force. Relative Strength.
How far can magnetic field reach?
The magnetic field of our planet — otherwise known as the magnetosphere — extends out to about 65,000 kilometers (40,000 mi) above the surface of the planet.
Which force has shortest range?
Strong nuclear force
Strong nuclear force has the shortest range inall fundamental forces.
Why electromagnetic force is a long-range force?
However, in an electret, there is an excess of positive or negative charge, resulting in the effects of the unbalanced charge extending well beyond the material. Thus, the electromagnetic force is indeed a long-range force, but in ordinary matter is usually balanced so that there are very few external effects.
Which is the shortest range force?
Strong nuclear force has the shortest range inall fundamental forces.
What is the unit of electromagnetic force?
It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge. In the electrostatic units of the centimetre–gram–second system, the unit of electromotive force is the statvolt, or one erg per electrostatic unit of charge.
What has electromagnetic force?
Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light.
Are black holes electromagnetic?
This hot mass of free electrons and nuclei is called a plasma. The trapped plasma forms the accretion disk of a black hole – a disk of material gravitationally bound to the black hole. As charged particles go around, they accelerate, causing the emission of electromagnetic radiation.
What are short range forces?
Short range forces happen when the centers of the molecules are separated by three angstroms (10-8 cm) or less. Short range forces tend to be repulsive, where the long range forces that act outside the three angstroms range are attractive. Long range forces are also known as Van der Waals forces.
What is the range of the weak force?
10−17 metre
The effectiveness of the weak interaction is confined to a distance range of 10−17 metre, about 1 percent of the diameter of a typical atomic nucleus. In radioactive decays the strength of the weak interaction is about 100,000 times less than the strength of the electromagnetic force.
Which is the highest magnetic force?
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.
How far can the strongest magnet reach?
It casts enough magnetic force to slow a locomotive from a quarter-million miles away–the distance of the Earth from the moon. The “magnetar,” or magnetic neutron star known as Soft Gamma Repeater 1806-20, is the most powerful known magnetic object in the universe.
Which is the longest range force?
gravitational force
Longest range force is gravitational force and nuclear force is shortest range force.
The electromagnetic force, also called the Lorentz force, explains how both moving and stationary charged particles interact.
How is electromagnetism related to modern physics?
Modern physics has unified the electromagnetic and weak forces into the electroweak force. A full understanding of the electromagnetic force and the full implications of electromagnetism takes many years of study. Some good places to go for more information on electromagnetism include hyperphysics.
Does electromagnetic force have an infinite range?
The electromagnetic force has infinite range, as does the gravitational force. Enjoy productive Java with IntelliJ IDEA. Discover instant and clever code completion, on-the-fly code analysis, and reliable refactoring tools.
What is the mass of photon in electromagnetic force?
The electromagnetic force is mediated by exchange of photon, which is massless. (There have been numerous attempts to measure the mass of photon and it has been found to be consistent with zero). The form of potential obtained by exchanging a particle is exp (-m r)/r where m is proportional to mass of exchanged particle.
