In electrochemical plating often a uniform deposition is desirable allowing to reduce both energy and material costs. Magnetic fields are well known to influence the mass transfer during electrolysis and offer easy control of the deposition process. In this paper, first, time-constant Lorentz forces are considered which, if properly designed, may considerably improve the uniformity of the deposit. Second, time-dependent Lorentz forces are investigated. It is demonstrated that pulsed deposition offers a comparable enhancement of the uniformity.
