Design and development of compliant mechanisms for electromagnetic force balance sensor
Precision engineering, 2020Compared with the lever-type amplifier, the rhombus-type amplifier has attracted more attention by virtue of large displacement amplification ratio, compact structure, and linear output displacement.

Electromagnetic Forces on a Superconductor
Physical Review, 1950Measurements of the eddy current damping of the rotational oscillations of a tin sphere suspended in a magnetic field from a torsion fiber give the expected results as a function of the magnetic field and the conductivity as long as the tin is a normal conductor.

IEEE transactions on magnetics, 2019
In this paper, a novel electromagnetic negative-stiffness spring (ENSS) is constructed by coaxial permanent annular magnets and coils with rectangular cross section. The stiffness of the ENSS is negative when the coils carry exciting current.

Electromagnetic Forces in Conductors
Journal of Applied Physics, 1967Relaxation-averaging formulas are derived for magnetic-induction problems involving axially symmetric fields with sinusoidal or pulsed time dependence in media which may be linear or nonlinear, homogeneous or inhomogeneous. Solutions have been obtained from a high-speed digital computer for time-harmonic fields in linear, inhomogeneous media.

Periodic root humps in thick-plate laser welding using steady electromagnetic force
Journal of Materials Processing Technology, 2019The transient and dynamic forming process of periodic root humps was observed using high-speed camera (CCD) and the ‘sandwich’ method. The formation mechanism of periodic root humps was analyzed.

Electromagnetic forces on contacts
2008 43rd International Universities Power Engineering Conference, 2008These instructions give you basic electromagnetic force on an arcing contact is one of the principal factors in designing large-capacity and small-sized high current contact systems of circuit breakers, disconnectors or isolated switches. Butt contacts, such as those in vacuum interrupters, tulip contacts structured from a rod contact and fingers are ...
