The basic difference between electric lines of force and magnetic lines of force
(A)Electric lines of force are perpendicular to the surface and magnetic lines of force originate from pole
(B)Electric lines of force do not intersect whereas magnetic lines of force intersect
(C)Electric lines of force intersect but magnetic lines of force do not intersect
(D)Magnetic lines of force are always in the form of closed loop whereas electric lines of force are always perpendicular to the surfaceCorrect
Answer: (D)
Solution
Magnetic lines are always closed loops (no isolated poles) while electric lines begin and end on charges and meet a conductor surface at right angles; neither type of line
