Question

A conducting bar of length 0.2 m and mass 11 g is suspended by a pair of flexible leads in a uniform 0.1 T magnetic field (directed into the page) as shown in the figure. What is the current required to remove the tension in the supporting leads? Supply a "-" sign if the current must flow from right to left.

The diagram illustrates a scenario in physics related to magnetic fields. Here’s a detailed explanation:

- **Top Section:** 
  - There are two horizontal lines, each represented with diagonal hatching. This likely indicates surfaces or materials, possibly representing poles of a magnet or charged plates.

- **Lines and Arrows:**
  - Two vertical wavy lines extend downwards from the top hatching, indicating the direction and path of forces or field lines. These lines appear to converge slightly towards the center, suggesting a focus or concentration of the field.

- **Bottom Section:**
  - A thick, black horizontal line stretches across the lower part of the diagram. This line could represent an object being influenced by the forces or fields from above. 

- **Background Pattern:**
  - The entire background is covered with regular, evenly spaced "X" marks. These symbols are typically used to represent a magnetic field directed into the page or screen. The consistent pattern suggests a uniform field.

Overall, the diagram is likely representing the concept of magnetic fields interacting with an object or plane, highlighting aspects like field direction and object orientation.
