Paramagnetic substances are magnestised ...

Paramagnetic substances are magnestised in a magnetic field in the same direction. Paramagnetism is due to the presence of

A

one or more unpaired electrons

B

all paired electrons

C

permanent spin and orbital motion

D

parallel and anti-parallel spins in equal number

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Paramagnetism:** - Paramagnetic substances are materials that exhibit a magnetic moment due to the presence of unpaired electrons. This means that when placed in a magnetic field, they tend to align with the field. 2. **Identifying Characteristics of Paramagnetic Substances:** - The key characteristic of paramagnetic substances is that they contain one or more unpaired electrons. These unpaired electrons contribute to the magnetic properties of the substance. 3. **Distinguishing from Diamagnetic Substances:** - It is important to differentiate paramagnetic substances from diamagnetic substances. Diamagnetic substances have all their electrons paired, which means they do not exhibit any net magnetic moment and are not attracted to a magnetic field. 4. **Conclusion:** - Based on the understanding that paramagnetism is due to the presence of unpaired electrons, we can conclude that the correct answer to the question is that paramagnetism is due to the presence of one or more unpaired electrons. **Final Answer:** Paramagnetism is due to the presence of one or more unpaired electrons. ---
