What is Elastic Hysteresis and How Does it Affect Electric Systems?

AI Thread Summary
Elastic hysteresis refers to the lag between applied stress and resulting strain in materials, while electrical hysteresis describes how a magnetic field applied to a metal causes dipole alignment, with the magnetic field lagging behind current changes. This lag can lead to energy loss in the form of heat, reducing the efficiency of electrical systems. The discussion highlights the confusion between magnetic and electrical hysteresis, with a focus on their effects on materials and energy loss. Understanding these concepts is crucial for applications in electrical engineering, particularly in the design of transformers and other electromagnetic devices. The relationship between input and output in hysteresis systems is influenced by their historical states.

Homework Statement



sorry just started my hnc in engineering and electrical the worst part for me

is this right

a current is applied a magnetic field is generated. current is reversed zeros its repeat. metal maintains degree of magnetizem dipole aligment. the magnetic field lags behind the current change. producing electreical hystersis loop.

The word "elastic" implies mechanical. The word "magnetic" implies magnetic hysteresis (like in the Wikipedia link I posted).

Can you please clarify what you are asking about? Do a Google search and find some links and diagrams that show what you are wanting to ask about, so we can try to help you understand. Thanks.

sorry i meant electrical
been trying to understand electrical hystersis for past 2 week and can't find simple definations for it
ive wrote about magnetic and electrical and mechanical
dont understand what electrical hystersis is

i thought electrical hysteresis was - magnetic field applied to metal produces alignments of dipoles and reverse back zero it retains memory of it, apply current to it the magnetic field lags behind the applied current.

i write amount magnet, elastic and electrical
a few lines each don't need many i wrote on it

i gave how heat given of u stretching rubber can cause degration within the polymer
and metals contain degee of elasticity so reform better than polymers

electrical hysterises
wrote about heat given off during hystersis can effect metal wiring rasising temperature decreasing curreny effeiency/running through the wire

dont kno wwhat to write for magnetic hystersis

Did you read the Wikipedia link that I posted in Post #2? :smile:

Ya thanks

i just think of negative effect of magnet hystersis like degration effecti got that for electrical hysterises degration

I'd have thought magnetic hysteresis was the easiest of the three.
Think about permanent magnets and remnance.
Think about applications like magnetic recording and magnetic memory,
Think about inrush currents and transformer design (and maybe other electromagnet machinery.).

can i just check
is that ok/correct understanding of it, what i wrote for electrical hystersis
Eletrical

In ferroelectric materials, Relenship between input and output of magnetic field and voltage. Voltage roduced lapses behind changing magnetic field. Present in metals. in Ferroelectric materials, in which the the polarity (storage of charges) lags behind the change in eletric field . when it repeat . it retain degree of polarity

Metal wires carring a current generates electrical hysterises producing heat, this course the current to have lower effieceny transfer of current so causing greater heat loss as well as the addition heat and energy loss from the

I'm sorry. Yes, I was talking of ferromagnetic materials. I see you are interested in ferroelectric materials.
I'm afraid I can't help much there.

no problem thank you for looking anyway

i found one,
polarised metal from magnetic hystersis increases degration of the metal by corrision

is this right for eletricl hystsersis

Elastic hysteresis. I have no idea on it. Looking for simple explanation for it.
The behavior of a system with hysteresis will depend on what happened to it in the past.
If you take away the magnetizing force from a piece of iron, the iron will remember it.
