Question

Consider the following statements.
$1$. Magnetic lines of force are closed curves while electric lines are not.
$2$. Electric lines of force are closed curves while magnetic lines are not.
$3$. Both electric and magnetic lines of force are closed curves.
Which of statement(s) given is/are correct?

• A. Only $2$
• B. Both $1$ and $2$
• C. Only $1$
• D. $1,2$ and $3$

Answer 1

The correct option is C Only $1$

Electric field lines of force always originate at the positive charge and terminate at the negative charge, so these do not form closed loop. On the other hand, magnetic field lines of force from a closed loop.
