Which coupling is desirable trait for good system design?
Low coupling
Is magnetic coupling or inductive coupling are same?
A plain mag coupler uses magnets to replace the field and armature coils in a brushless dc motor. Then two shafts are coupled together, but to remain coupled they have to be synchronous (rotating at the same speed). If one shaft has a drive motor and the other has the load (fan blades for example) if the load exceeds the maximum torque they slip and are no longer coupled together (the blades will stop turning until the motor stops and restarts). A mechanical inductive coupling has a squirrel cage similar to an induction motor. This allows the transmission of torque without having to have the same speed. Also, inductive coupling can refer to transmitting electrical power through coupled inductors or a transformer.
What are the types of coupling in software engineering?
control coupling content coupling common coupling data coupling external coupling message coupling
What are types of mechanical coupling?
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
Comparison between fluid coupling and torque converter?
They are of similar design, but a fluid coupling simply transmits torque (with some frictional loss), while a torque converter amplifies torque, similar to a reduction gear.

Low coupling
What is the difference between inductive coupling and capacitive coupling?
A capacitor is a device that resists a change in voltage, proportional to current and inversely proportional to capacitance. dv/dt = i/c An inductor is a device that resists a change in current, proportional to voltage and inversely proportional to inductance. di/dt = v/l In an AC circuit with capacitive loading, the current waveform will lead the voltage waveform; while with inductive loading, the current waveform will lag the voltage waveform.
What are the minimum amount of winding of coil for inductive coupling to take place between two metal coils?
Not even a single turn, just having two wires "near" each other will cause some inductive coupling between them. This is one of the causes of "crosstalk" that causes signal to appear in weakened form on wires they don't belong on (the other cause is capacitive coupling, which is also present between any two wires "near" each other).The real matter is how much coupling you want (or can tolerate, if you don't want coupling).

Why there should be low coupling and high cohesion in software design?
There should be low dependence and high interaction between the modules. The dependence should be low so that the module can work in absence of another module. So, there should be low coupling ad high cohesion in software design.

How many type of coupling?
For most parts of electronics is concerned,there are two types of coupling in any alternating current source (AC) circuits: 1)capacitive coupling(Also known as the AC coupling) 2)Inductive Coupling(Also known as the Transformer coupling) Two circuits of different amplification factors and different hybrid parameter values can be merged or coupled by means of a capacitor (capacitive coupling) or an inductor or a transformer (inductive coupling).There are coupling coefficients involved with the transformer.But Capacitor blocks DC and allows AC most of the time.We use ceramic capacitors for this purpose.However never replace the ceramic capacitor with an electrolytic capacitor .Electrolytic capacitors are strictly polar while ceramic capacitors are not.Electrolytic capacitors are used as bypass capacitors.They bypass the current from the resistances that are parallel to them during high frequencies.This is so because the reactance of the capacitor is low at such high frequencies.Also current takes the least resistance path.As reactance gives the AC equivalent of the resistance,current flows into the capacitor while resistance and capacitors are connected end-end and thus the current reaches the other node(its like a diversion or a detour or a shortcut on the road for vehicles-analogously it is the simplest path a current can follow on the conductor
What is a qualitative historical design?
Qualitative historical design can be briefly enumerated as thus_ Methods of data collection and analysis. The use of such strategies which includes inductive and deductive inquires.Qualitative historical design focuses mainly on inductive reasoning such as iterative,multifaceted, and also simultaneous reckonings or reasonings. However it can also be defined as series of contradictions,hesitations,and tensions.All these contradicts or contrasts the Quantitative methodologies.
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
How wireless chargers are working?
Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.
