Answer:
Explanation:
Given
Current in the conductor [tex]i=8.75 A[/tex]
maximum Force [tex]F=1.28 N[/tex]
If Poles Faces are 55.5 cm in diameter i.e. Length [tex]L=55.5 cm[/tex]
Force experience by a current carrying conductor is given by
[tex]F=Bil[/tex]
where [tex]B=magnetic\ Field[/tex]
[tex]i=current [/tex]
[tex]F=force[/tex]
[tex]1.28=B\times 8.75\times 0.555[/tex]
[tex]B=0.263 T[/tex]
thus Strength of Magnetic Field is 0.263 T
