Now-a-days magnets are made of

Options

A. Iron
B. nickel
C. both (a) and (b)
D. copper

Explanation

**Step-by-Step Solution:**

1. **Understanding Magnetic Materials**: Magnets are made from materials that are classified as magnetic materials. These materials can be attracted by magnets or can be magnetized themselves.

2. **Identifying Magnetic Materials**: The common magnetic materials include iron, nickel, and cobalt. These materials possess the property of being attracted to magnets.

3. **Evaluating the Options**: The question provides four options:
- A) Iron
- B) Nickel
- C) Copper
- D) Iron and Nickel both

4. **Analyzing Each Option**:
- **Iron**: This is a magnetic material and can be used to make magnets.
- **Nickel**: This is also a magnetic material and can be used to make magnets.
- **Copper**: This is a non-magnetic material and cannot be used to make magnets.
- **Iron and Nickel both**: Since both are magnetic materials, this option is valid.

5. **Conclusion**: The correct answer is that magnets can be made from iron and nickel, which corresponds to option D (Iron and Nickel both).

**Final Answer**: The correct answer is option D (Iron and Nickel both).
