A peak time shifting phenomenon in transformer axial short‐circuit electromagnetic force due to the coupling of electromagnetic‐axial vibration [PDF]
Abstract Accurately calculating axial electromagnetic force is essential to analyse transformer winding axial stability. Prior research has mainly focused on the effect of winding structure on static axial electromagnetic force and studying vibration by substituting the static force in a time‐varying function.

Electromagnetic Force Distribution and Forming Performance in Electromagnetic Tube Expansion with Axial Compression [PDF]
Electromagnetic tube expansion has been given much attention due to its superior cold forming properties. The traditional electromagnetic coil is of single structure, which results in substantial tube wall thinning and mechanical strength reduction.

Radial-axial Force Controlled Electromagnetic Sheet Deep Drawing: Electromagnetic Analysis [PDF]
AbstractA new approach, radial-axial force controlled (RAFC) electromagnetic sheet forming (EMF), has been developed for hard-form metal sheet deep drawing. Different to the traditional EMF, an additional radial Lorentz force was introduced at the flange region of workpiece to improve the material flow and reduce the maximum strain of workpiece.
