Which of the field patterns given below is valid for electric field as well as for magnetic field?

(A)(see structure)
(B)(see structure)
(C)(see structure)
✓ Correct
(D)(see structure)

Answer: (C)

Solution

Electric field lines can begin and end on charges (diverge from positive, converge to negative). Magnetic field lines always form closed loops (no magnetic monopoles). Option (C) shows closed loops, which is valid for both electric field (around a current-carrying wire or in certain configurations) and magnetic field. Options showing lines that terminate are only valid for electric fields.
