- A thin stiff insulated metal wire is bent into a circular loop with its two ends extending tangentially from the same point of the loop. The wire loop has mass \( m \) and radius \( r \) and is in a uniform vertical magnetic field \( B_0 \). When a current \( I \) is passed through the loop, the loop turns about the line PQ by an angle \( \theta \). The angle \( \theta \) is given by:

Packing Efficiency
The percentage of total space in a unit cell that is filled by the constituent particles, such as atoms, ions, or molecules, packed within the lattice is called the packing efficiency. It is the total amount of space engaged by these particles in three-dimensional space. In a simple manner, we can understand it as the specified percentage of the total volume of a solid which is occupied by spherical atoms. Packing Efficiency can be evaluated in three structures with the help of geometry which are:
- Cubic Close Packing and Hexagonal Close Packing.
- Body-Centred Cubic Structures
- Simple Lattice Structures of Cubic
Following are the importance of packing efficiency:
- It represents the solid structure of the object.
- It displays different properties of solids such as consistency, density, and isotropy.
- Different attributes of solid structures can be derived, with the help of Packing Efficiency.
