The newest relationships from fuel and you will magnetism are difficult to spell it out inside nontechnical terms. This really is for the reason that one should define brand new interactions into the regards to hidden „push areas“ and therefore shift, develop, contract, strengthen, damage, and you can become in dimensions, and these are hard to describe acceptably during the spoken terminology. When you look at the statistical terminology, coupled groups of three-dimensional vector differential equations are needed, and these are also very hard to visualize.
Therefore, we’ll go white toward mathematics once we talk about Elizabeth M. We are going to have confidence in alot more easy to use, graphical interpretations. Here you will find the principles:
F = k q 1 q dos / r dos where: k = brand new electrostatic lingering = 8.99 X ten nine kg meters step 3 / s 2 coul 2 , r = the length between the two charge, and you can q step 1 and q 2 could be the a few charge, counted during the coulombs. (One coulomb = the charges on six.24 X ten 18 electrons. Thus, you to proton or electron deal a charge out of ±step 1.602 X 10 -19 coulomb.) In the event the q 1 and you may q dos have a similar herpes dating Italy app signal, brand new electrostatic force try repulsive. If they have contrary cues, the newest push is of interest. Find how the formula to possess electrostatic force appears just like one to possess the law of gravity: most of the we have to create was replacement the latest gravitational lingering G to your electrostatic constant k, and option bulk to own charge.
2) Fixed magnetic fields aren’t explained because of the a straightforward formula, because magnets will have a northern pole and you may a-south rod, so the magnetic occupation constantly loops from 1 rod with the other. If one immerses a magnetic in a heavy water that contains metal filings, and you can shakes the container, the new iron filings commonly make on their own along the magnetic career and for this reason show the shape of one’s profession.
