What are the properties of magnetic lines of force?

i) They form closed loops, ii) The direction of the net magnetic field at a point is given by the tangent to the magnetic line of force at that point, iii) The number of lines of force crossing per unit area decides the magnitude of the magnetic field, iv) They do not intersect Signup and view all the answers

Compare the formation of magnetic lines of force with electric lines of force.

Magnetic lines of force form closed loops, while electric lines of force originate from the positive charge and end on the negative charge without forming a complete loop. Signup and view all the answers
