Web12 apr. 2024 · Detection: As it does not interact with the electromagnetic force, thus it does not absorb, reflect or emit light or electromagnetic radiation of any kind. And this makes it extremely hard to spot/detect. It can be detected only through its gravitational effects. Importance: Its gravitational force prevents stars in our Milky Way from flying apart. Web11 apr. 2024 · Faraday’s Law of Electromagnetic Induction. When a magnetic field changes within a closed loop of wire, an EMF is induced in the loop. Faraday’s Law can be used to calculate the induced EMF: EMF = -N * (ΔΦ/Δt) Where: N is the number of turns in the coil; ΔΦ is the change in magnetic flux; Δt is the change in time; Kirchhoff’s Loop Rule

WebUnlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750. If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value. WebIf we have both electric and magnetic fields, the total force that acts on a charge is of course given by F~ = q E~ + ~v c ×B~!. This combined force law is known as the Lorentz … office chairs ct
