Question

The magnetic circuit below is excited by a 100-turn coil wound over the central leg. The mean length of the central leg is 5.5cm; the mean length of outer paths (including the part of the iron bar at the bottom) is 15.5cm. The relative permeability of the magnetic material is 2000. The cross-sectional area of all legs is A

Answer 1

Answer:

Hello your question is incomplete attached below is the complete question and solution

answer;

attached below

Explanation:

Given data:

100-turn coil

mean length of central leg = 5.5 cm

mean length of outer paths = 15.5 cm

relative permeability = 2000

cross sectional area ( A ) = 1 cm^2

distance x = 1 cm
