Determine the inductance of a solenoid with 650 turns in a length of 28 cm . The circular cross section of the solenoid has a radius of 3.5 cm .

The value is      

Explanation:

From the question we are told that

    The number of turns is  

     The length is  

      The radius of the cross-section is

Generally the cross-sectional area  is mathematically represented as

=>    

=>    

Generally the inductance is mathematically represented as

Here   is the permeability of free space with value

=>    

=>          

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
