Question

The electric and magnetic field differ in that :

• A. the electric lines of force are closed curves, while magnetic field lines are not
• B. the magnetic field lines are closed, while electric lines are not
• C. the electric lines can give direction of electric field, while magnetic lines cannot
• D. the magnetic lines can give direction of magnetic field, while electric lines cannot

Answer 1

The correct option is B the magnetic field lines are closed, while electric lines are not

Electric field lines are either converging towards a point or diverging from a point.
Whereas, magnetic field lines forms a closed loop.
Electric lines can give give both direction and magnitude of electric field.
Magnetic field lines can also give both direction and magnitude.
