Take a bar Magnet and put s on a cardboard. Spnnithe iron filings around the bar magnet Bar magnet applies force on won filings scattered on the cardboard. Due to this twee they move and rearrange themselves in a pattern.

In other words we can say that 'magnet creates magnetic field in Ws money. This magnetic field applies force on iron fangs and a pattern is made.'Drawing Magnetic Field Lines using Magnetic Compass Needle and Bar MagnetTake a Bar magnet_ Put the compass needle nearby. The north pole of the magnet wit attract the sect bp of the co pass needle. Move the compass needle sknAy and mark the points. Now join all the points from north to Scot Pole. This wit give the direction of Magnetic field.

Thus. we can also say that.The direction of magnetic field at a point is the direction of resultant force acting on a hypothetical north pole placed at that point.Prournie, of Magnetic Field Line,Magnetic field lines originate from Nosh Pole and end at South Pole.II. Magnetic field lines come dose, to one another near the poles of magnet but WO* separated at Other places.Ill. Magnetic field lines do not intersect each other.Nola: Magnetic held Ines never intersect each other because resultant force at North Pole can onty be in one direction. had the Ines intersected. a would be +1Modirections intik!, not possible.
