Permanent magnets are generally made of alloys of

Options

A. Co
B. Zn
C. Mn
D. Pb

Answer

To answer the question "Permanent magnets are generally made of alloys of," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Permanent Magnets**:
- Permanent magnets are materials that can be magnetized and maintain their magnetic properties over time without the need for an external magnetic field.

2. **Identifying the Components of Alloys**:
- An alloy is a mixture of two or more elements, where at least one is a metal. Common elements in alloys can include metals, non-metals, and metalloids.

3. **Common Elements in Permanent Magnets**:
- The most common elements used in the production of permanent magnets are iron (Fe), nickel (Ni), and cobalt (Co). These metals are known for their ability to be magnetized easily and retain their magnetism.

4. **Conclusion**:
- Therefore, permanent magnets are generally made from alloys of iron, nickel, and cobalt.

### Final Answer:
Permanent magnets are generally made of alloys of iron (Fe), nickel (Ni), and cobalt (Co).
