WebYes, there are magnetic fields in space. The spiral arms of the Milky Way seem to have some very large-scale organised magnetic field on the basis of studies of large numbers of pulsars and the polarisation of their radio signals. Interstellar dust clouds have been found to have magnetic fields. As these clouds collapse, the fields are amplified.
WebThe magnetic vector potential (\vec {A}) (A) is a vector field that serves as the potential for the magnetic field. The curl of the magnetic vector potential is the magnetic field. \vec {B} = \nabla \times \vec {A} B = ∇×A The magnetic vector potential is preferred when working with the Lagrangian in classical mechanics and quantum mechanics. modway wicker furnitureWebA light beam of wavelength is 4 0 0 n m is incident on a metal plate with work function 2. 2 V. a) A particular e − absorbs a photon and makes two collisions before coming out of the metal assuming that 1 0 % extra energy is lost to the metal in each collision.
