Hey!✌ CONTENT QUALITY REQUIRED✌Who can answer my question......?Explain in detail about ELECTROMAGNETIC FORCE and Absolute PERMITTIVITY Of FREE SPACE.It's quite urgent......#No spamming.11th physics chapter: "PHYSICAL WORLD".

Answer»

Electromagnetic Force--
the electromagnetic force is the force which acts between charged particles and is the combination of all electric and magnetic force.the electromagnetic force can be attractive or repulsive. it has infinite Range.
Although its strength is universily propotional to the square of distance (that is doubling the distance between TWO charged particles decreases the force between them by a factor of 4).

Why does magnetic field lines form closed loops?

Answer»

Gauss’ law of magnetism states that “ The MAGNETIC flux though any closed surface is ZERO “ .

This is just another way of saying that magnetic mono-poles do not exist, and that all magnetic FIELDS are actually generated by circulating currents.

An immediate corollary of the above law is that the number of magnetic field-lines which enter a closed surface is always EQUAL to the number of field-lines which leave the surface. In other words:

Magnetic field-lines form closed loops which never begin or END.

Fick first law of diffusion vs 2nd law of diffusion

Answer»

Fick's laws of diffusion describediffusion and were DERIVED by AdolfFick in 1855. They can be used to SOLVE for the diffusion coefficient, D.Fick's FIRST LAW can be used to DERIVE his second law which in turn is identical to the diffusion equation.

Difference btw active and passive transducers

Answer»

Hey.... here your answer____________________

PASSIVE TRANSDUCERS :- These are those transducers that derive the power required for transduction from an additional power source. Other name is “externally powered transducers “. Examples of passive transducers are : all resistive, Inductive and capacitive transducers.

A most common example is a POT ( used for measurement of displacement).

【figure on the left】

From the above figure, let x′x′be the full length of pot. And E is the additional power source, so the output voltage EoutEout will be equal to ((x/x′)∗E.x/x′)∗E.as you can see that in the absence of E (external power source) output voltage will be equal to zero. HENCE, this is CALLED passive transducer.

ACTIVE TRANSDUCERS :- These are those that do not require any additional power source to produce their output. Other name “SELF generating type “. Examples of these transducers are thermocouple, photovoltaic cells (solar cells)•

You can take any example like solar cells that do not require any other source except solar energy (light energy) , as shown below:-

【figure on right】

hence they are known as active transducers.

I hope it will helpful to u
