Answer #1

Magnetic field produced by loopt at loop 2 is Bra Ho Is ap 2 - 2 a ² + 221312 Flux passing through (2) is d = B. Az = Hol, a,

Unit of mutual indunctance is Henry

Matlab code

1 clc; 2 close all; 6 0 = 1.257e-6 #Henter/meter vaccuum permeability 8 9 al = 0.01; a2 = 0.04; #given radius d = 0.1; % dist

Output

Command Window u0 = 0.0000012570 M = 0.00000000031124 >> |
