 It is desired to store 100 nJ in a solenoid inductor. 
a)  Given that the maximum current that can be obtained is 1A, what should be the value
minimum of inductance to get this energy?
b)  If the volume of this inductor must be less than 0.5 cm3
 propose realistic values for radius, length and number of turns to get the value calculated in a).
c) Using the values ​​proposed in b), what is the maximum diameter that the wire can have to make the inductor?
