Plz tell me in detail that what is magnetic circuit.It‘s uses tell ma the operations construction of any magnetic circuit.
A magnetic circuit would be multiple magnetic flux pathways in series/parallel. These things are being used in integrated magnetics for switching power supplies, magnetic amplifiers, flux gates etc They are also somewhat esoteric and their application requires a fairly deep understanding of magnetics. I don't think that is what you are talking about, is it? I don't know of a simple qualitative explanation for how these things work and the a quantitative treatise would have the size of a dissertation or small monograph. Neither is fitting for Yahoo answers. Not to mention that it would most likely not satisfy your curiosity, which, if I am not mistaken, is about something completely different. I just can't tell what. But if you can be more precise, I could answer in more detail.
normally if a wheel cylinder is bad it will leak other wise it dont really go bad outside of that, that ive heard of. you have enough fluid in it, and the fluid is clear looking? adjust the brake pads or whatever you have on the back maybe it is just adjusted to close to it. check the cables make sure they are ok and working good.
Brake shoes not adjusted? Primary and secondary shoe swapped? All return springs in the right places and secure? Generally, a bad wheel cylinder leaks brake fluid. It's not too common for them to stick.
Magnetic circuits is dealing with magnetic field instead electric field. When u r dealing with transformers, motors etc, where a magnetic core is used. It is sometimes interesting to note that ferrite core which is used in transformer is a non-conductor of electric current but a good conductor of magnetic fields. So we need magnetic circuits to do our analysis. some analogy are Flux current, MMFvoltage, reluctanesresistances. Also during the construction of a magnetic circuit, our main aim is in the analysis of the core and its coupling effects and its energy transfer properties .
George T is half right, it's a Buick and do replace both if one is leaking. Remove drum and with a small screw driver lift the rubber cap up from the wheel cly, if there's any fluid behind them replace them. If not look at the M/C where it is bolted to the power booster and look for stains running from the back of the MC down the frt. of power booster, if so replace the M/C.
