Questions
A parabolic section of wire OA is located in the x-y plane and carries current I = 12 A. A uniform magnetic field B = 4.0 T making an angle 600 with x axis exists in x-y plane. Calculate the magnetic force on the wire OA. Coordinates of A are (0.25 m, 1 m).
detailed solution
Correct option is A
Magnetic field is uniform, apply F→=lL→ × B→ where L→ = 0.25 i^+j^ and B→ = 4cos 60i^+sin60j^ =2i^+23j^ Therefore F→=6(3 -4)k^ NTalk to our academic expert!
