There is a force on the plunger required to do to move it into or out of the gap and work must be done by or against this force. The conservation of energy dictates that the change in the electrical energy stored in the magnetic field equals the work done in moving the magnetic material in or out of the core.
(It is usually assumed that the current will be kept constant as the plunger moves, so I is independent of x)
What are hard magnetic materials? Hard Magnetic materials- They have a slowly rising magnetization curve along with large hysteresis loop area and therefore large energy losses
Three Logic Levels are used and they are High, Low, High impedance state. The high and low are normal logic levels & high impedance state is electrical open circuit conditions. Tri
develop and explain series and parallel magnetic circuits?
The following data apply to a 100-kW, 250-V, six-pole, 1000-r/min long-shunt compound generator: no-load rotational losses 4000 W, armature resistance at 75°C = 0.015 , series-fie
Q. Write a brief note on common drain amplifier Since voltage at the gate-drain is more easily determined than that of the voltage at gate-source, the voltage source in the inp
Hysteresis results in a dissipation of energy Hysteresis results in a dissipation of energy which appears as a heating of the magnetic material. The energy loss associated wit
Q. For the circuit of Figure: (a) Find an expression for the power absorbed by the load as a function of RL. (b) Plot the power dissipated by the load as a function of the lo
