http://ece.rice.edu/~jdw/435/book/ch9.pdf Webforce was actually acting on the iron of the armature, and not on the armature coils. In some cases, there is no visible current on which the magnetic field can even appear to act. A fa-miliar example of this is the force produced when picking up a nail with a magnet, either a perma-nent magnet or an electromagnet.

Web12 sep. 2024 · The acceleration is calculated from the net force from the magnetic field, equal to mass times acceleration. The magnitude of the acceleration is: (11.7.9) m a = q v B (11.7.10) a = q v B m = ( 1.6 × 10 − 19 C) ( 3 × 10 6 m / s) ( 2 × 10 − 3 T) 0.1 × 10 − 31 k g = 1.1 × 10 15 m / s 2. WebThe magnetic field exerts a Lorentz force on the electron (pink arrow) of F1 = −e(v × B), where e is the electron's charge. Since the electron has a negative charge, from the right hand rule this is directed in the +z direction.
