Artificially designed magnets ____.

Options

A. can be made in different shapes.
B. can be made stronger than natural magnets
C. can have more than two poles
D. Both (a) and (b)

Explanation

**Step-by-Step Solution:**

1. **Understanding Artificially Designed Magnets:**
- Artificially designed magnets are magnets that are created by humans, as opposed to natural magnets which occur in nature. They can be made in various shapes and sizes.

2. **Different Shapes of Artificial Magnets:**
- Artificial magnets can be manufactured in different shapes such as bar magnets, cylindrical magnets, and hexagonal magnets. This versatility in design allows for specific applications in various fields.

3. **Strength of Artificial Magnets:**
- One of the advantages of artificially designed magnets is that they can be made stronger than natural magnets. The strength of a magnet depends on the material it is made from and its cross-sectional area.

4. **Poles of Magnets:**
- All magnets, whether natural or artificial, have two poles: a north pole and a south pole. It is important to note that magnets do not have more than two poles; they always come in pairs.

5. **Conclusion:**
- Based on the information, we can conclude that artificially designed magnets can be made in different shapes and can be stronger than natural magnets. However, they cannot have more than two poles.

**Final Answer:**
- Artificially designed magnets can be made in different shapes and can be stronger than natural magnets (Options 1 and 2 are correct).
