Therefore, this paper deduces calculative formula in open-loop problem and finds that the effect of displacement current is the key reason. The method of magnetic vector potential with displacement current is proposed. Analytical analysis and numerical experiment are given and show that validity of ...
The Nd–Fe–B magnets are based on theintermetallic compoundof the formula Nd2Fe14B. The interest in these magnets is due to the fact they are stronger than other materials and of low cost. The magnetic energies and costs of the most common magnetic materials as of 1986 are presented inTa...
The analytical formula in Eq. (3), and the parameter values can be found in “Experimental designs”. Full size image Results Free energy amplification by the magnetic field We consider a closed quantum system of a particle with mass m and charge q. The notations p, x are the momentum ...
The most commonly used soft magnetic oxides are the ferrites of the spinel structure, having the formula TO·Fe2O3 where T is a divalent transition ion. In this structure the Fe+3 and T+2 ions can occupy two types of sites having different oxygen coordination: tetragonal “A” sites and...
Flexible electronics has manifested exploration and development of potential energy efficient technologies like ultrathin sensors, actuators, wearable electronics and new generation straintronic devices in recent years1,2,3,4,5,6,7,8,9,10,11,12,13. The ability of these electronics to bend, stretch...

The design parameters for the hold-off time are: the core material; the cross sectional area; and the number of turns. The hold-off time can be calculated with the formula: ∫V dt=N AeuΔB Where V is the applied voltage, N is the number of turns, B is the magnetic flux density ...
