[QUOTE="Fatima Hasan, post: 6005987, member: 637572"] [h2]Homework Statement [/h2] A wire carrying current I=7A is shaped as half circle of radius R=0.2m.The magnetic field B(in μT) at the center is : A)11.0(k) B)7.9(k) C)9.4(k) D)6.3(k) E)4.0(-k) [h2]Homework Equations[/h2] B=(μ[SUB]0[/SUB] I)/(2πR) [h2]The Attempt at a Solution[/h2] B = (4π*10[SUP]-7[/SUP] *7)/(0.2*2*π) * 0.5 (Multiply by 1/2 because the wire is shaped as half circle). B = 3.5*10[SUP]-6[/SUP] T = 3.5μT Could anyone tell me where is my mistake? [/QUOTE]
