For example, P. K. Srivastava (2004). Mechanics. New Age International Pub. (P) Limited. p. 94. ISBN9788122411126. Retrieved 2018-11-20.: "In general, a force which depends explicitly upon the velocity of the particle is not conservative. However, the magnetic force (qv×B) can be included among conservative forces in the sense that it acts perpendicular to velocity and hence work done is always zero". Web link
