Magnetic Flux Density Direction

Click For Summary
SUMMARY

The direction of the Magnetic Flux Density vector B is towards the south pole on the south side and out of the north pole on the north side. Both representations of the magnetic field are accurate, despite the presence of additional arrows in one figure. Magnetic flux density, often referred to as the magnetic field B, is defined as the magnetic flux through an area divided by that area, confirming its status as a vector quantity. This clarification emphasizes that magnetic flux density is not merely a property but a vector with a specific direction.

Would the direction of the Magnetic Flux Density vector B at the south side be towards the south pole like this?

and is the direction for B correct for the other side?

One more thing, how can magnetic flux density be a vector and have a direction when its sort of a density, I mean its over an area, how can you make that a single vector? Its sort of like a property.

1. I don't see the difference between the two figures, except that you drew two extra arrows. Both figures are correct. The field is toward the south pole, and out of the north pole.
2. Don't read too much into the name. The same "flux density" is also called the magnetic field B. The magnetic flux through an area is defined as the magnetic field multiplied by the area (actually a dot product between B and the area vector A). So if you want to call magnetic field as the magnetic flux divided by the area, and thus call it the magnetic flux density, so be it. It is still the magnetic field, and is an honest to goodness vector.
