Web20.6. This equation gives the force on a straight current-carrying wire of length ℓ in a magnetic field of strength B. The angle θ is the angle between the current vector and the magnetic field vector. Note that ℓ is the length of wire that is in the magnetic field and for which θ ≠ 0, as shown in Figure 20.19. WebThe direction of the magnetic force F F is perpendicular to the plane formed by v v and B B, as determined by the right hand rule 1 (or RHR-1), which is illustrated in Figure 22.16. RHR-1 states that, to determine the direction of the magnetic force on a positive moving charge, you point the thumb of the right hand in the direction of v v, ...

WebJan 13, 2024 · The magnetic force on any single charge carrier is e v → d × B →, so the total magnetic force d F → on the n A ⋅ d l charge carriers in the section of wire is. (7.5.2) d F → = ( n A ⋅ d l) e v → d × B →. We can define dl to be a vector of length dl pointing along v → d, which allows us to rewrite this equation as. WebPhysicists use a hand mnemonic known as the right-hand rule to help remember the direction of magnetic forces. To form the mnemonic, first make an L-shape with the thumb and first two fingers of your right hand. Then, point your middle finger perpendicular … refurbished 6s plus verizon
