A uniform magnetic field is a magnetic field that has the same magnitude and throughout the region under consideration,.

Figure shows a loop model (loop $L$ ) for a diamagnetic material. (a) Sketch the magnetic field lines within and about the material due to the bar magnet. What is the direction of (b) the loop's net magnetic dipole moment $\overrightarrow{\mu },\left(\mathrm{c}\right)$ the conventional current $i$ in the loop (clockwise or counterclockwise in the figure), and the magnetic force on the loop?

If the magnetic lines of force are shaped like arcs of concentric circles with their centre at point $\mathrm{O}$ in a certain section of a magnetic field:

A magnet  $AB$ is placed near an iron bar X. Name the poles at  $A$ and $B$. How do you draw your conclusion?
