Step 1: Understanding the Concept:
Materials are classified into three main types based on their behavior when placed in an external magnetic field. This behavior is determined by their atomic structure and is quantified by their magnetic susceptibility (\(\chi\)).
Step 2: Detailed Comparison:
The key differences between diamagnetic, paramagnetic, and ferromagnetic substances are summarized in the table below. 
The path of scattered \( \alpha \)-particle is:
The maximum focal length of convex lens is for:
The power consumed in alternating current in a circuit containing only a capacitor will be:
