Question

List 5 characteristics of uniform and nonuniform magnetic field in physics.

Answer 1

Answer:

Magnetic Field Lines or Magnetic Lines of Force The path made by a compass needle in going it from one end of the bar magnet to another end, then magnetic lines of force may be defined as the curve, the tangent at any point gives the direction of the magnetic field at that point. It may also be defined as the path along which a unit north pole would tend to move if free to do so. Magnetic lines of force are shown in figure 8.7.

Properties  

1. The magnetic field lines of a magnet forms continuous closed loops.  

2. They start in air from the N-pole and end at the S-pole and then return to the N-pole through the interior of the magnet.  

3. The tangent to the field line at a given point represents the direction of the net magnetic field B at that point.  

4. The magnetic field lines do not intersect each other. If they do so, that would mean there are two directions of the magnetic field at the point of intersection, which is impossible.  

5. The larger the number of field lines crossing per unit area, the stronger is the magnitude of the magnetic field. Near from poles, the magnetic field is stronger and far from poles, the magnetic field is weak.  

6. In uniform magnetic field, magnetic field lines are at parallel and at same distance.
