Bookmark or Share- The Electric Field - Physics - SocraticA force field is a way to picture the effects that electric charges have on one another. Instead of talking about the force that a positive charge exerts on an electron, we can say the charge creates a force "field" in the empty space around it. An electron put down at any place in this force field is pulled towards the positive charge; a positive charge set down at the same place is pushed away.
- What are field forces in physics? + Example - SocraticWhen a body exerts an influence into the space around itself, we say that the body creates a " field " around itself. I tried to look up "field forces" but found nothing related to Physics given that phrase. I will assume you mean "force fields". When a body exerts an influence into the space around itself, we say that the body creates a " field " around itself. There are 2 examples in Physics ...
- Electric Force - Physics - SocraticElectric Force = ke ⋅ |q1 ⋅ q2| r2. Where r is the distance between the charges, q1 and q2 are the magnitudes of the two point charges, and ke = 8.99 × 109N ⋅ m2 C2, is a constant of proportionality called the Coulomb constant. The equation above is a simplified version of Coulomb's Law; more specifically it is the scalar form.
- Magnetic Force - Physics - SocraticA magnetic force is the attraction or repulsion that arises between electrically charged particles because of their motion; the basic force responsible for the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; and both electric and magnetic forces exist among moving electric charges. This force is usually measured in ...
- How does distance affect magnetic force? - SocraticMagnetic force obeys an inverse square law with distance. The equation for magnetic force is similar to Coulomb's Law (if you are familiar with it). But the key point is that the force is inversely proportional to the distance squared (i.e. it obeys an inverse square law with distance). (Fprop 1/r^2) Where r is the distance between the magnets. What that means in practical terms is the ...
