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. WebSep 3, 2024 · In macroscopic EM theory is that magnetic force on magnetized body element free of in-bulk electric current (basic nonconductive magnet) is given by the formula: F = − m ⋅ ∇ B e x t. Thus force is non-zero only if the magnetic field varies with position in space. WebSo suppose I have a U-Shaped electromagnet with a known magnetic fields strength (in Tesla), How do I calculate how much force (In Newtons) It will exert on an object that is attached to it. The object is a small flat piece of iron that hangs on the magnet vertically. Physics Physical science Natural science Science. 0 comments. cinvestav math
