Magnetic Circuit with Air Gap || Example 1.1 || Practice Problem 1.1 || EM (Ch-1)(Fitzgerald)

EM (Ch-1)(Fitzgerald) - Example 1.1 and Practice Problem 1.1

Example 1.1: The magnetic circuit shown in Fig. 1.2 has dimensions Ac = Ag = 9 cm 2, g = 0.050 cm, lc = 30 cm, and N = 500 tums. Assume the value/J.r = 70,000 for core material. (a) Find the reluctances 7-¢.c and 7"¢.g. For the condition that the magnetic circuit is operating with Bc = 1.0 T, find (b) the flux 4) and (c) the current i.

Practice Problem 1.1 : Find the flux 4) and current for Example 1.1 if (a) the number of turns is doubled to N = 1000 turns while the circuit dimensions remain the same and (b) if the number of turns is equal to N = 500 and the gap is reduced to 0.040 cm.

The video describes magnetic circuit with air gap. Problem 1.1 and Practice Problem 1.1, Electric Machinery book is also explained.

once again gracias for good work you've done for us

[mdwashimakram]

I am so very satisfied about air gap math

[coldwinternj]

Thanks so much Sir, I appreciate your teaching.

[siphesihlesiphesinenhlanhl]

when you get time please do this type of question that include the % in the gap

gracias in advance

[akbardehghani]

sir, Why does the magnetic flux remain constant as the air gap length (g) decreases or increases in the magnetic circuit where the AC voltage source is connected to the coil? and we only have current changes?

[muhammadnasranbinmohdnoor]

sir, is the flux in the air gap is the same with the flux in the core?

how can i get answer if iron magnetic permeability is 0?
