Question

define magnetic lines of force and give their two main properties
​

Answer 1

Answer:

Magnetic lines of force have a number of important properties, which include: They seek the path of least resistance between opposite magnetic poles. In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole. They never cross one another. They all have the same strength.

Answer 2

The curves which are used to represent the magnetic field, such that the number of lines represent the strength of the magnetic field at any point are called magnetic lines of force. The direction of magnetic force is given by the tangent of the curve at any point.‼️
