What is the direction of magnetic field lines in a non uniform magnetic field? iii ) What does closely placed magnetic field at a point represent ? iv) Magnetic field lines are parallel to each other at distant points from a bar magnet .Why? *
Answers
Magnetic fields is non-uniform if its magnitude is not equal and direction is not same every point in space. The direction of magnetic field is taken to be the direction in which a north pole of compass needle move inside it. Magnetic field lines emerges from North pole and enter the magnet at south pole.
The direction of field lines represent the direction of force a body would experience around Earth, and the density of field lines (how closely they are separated) represents the strength of the force. ... A compass, which is a small magnet itself, lines up parallel to the magnetic field lines at the point it is placed.
Eventually, the strength of the magnetic field is strong where the lines are closer and they weaken as they closeness decreases. Hence, if the field lines in a magnetic field are parallel and equidistant, the magnetic field is uniform.
