The best way is: B. flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down.
<h3>What is the law of magnetism?</h3>
The law of magnetism states that the like poles of a magnet repel one another while unlike (different) poles attract each other. Thus, two north (N) poles of a magnet would repel one another while a north (N) and south (S) would attract each other.
Based on the law of magnetism, the best way to arrange the magnets on the train and on the track, so as to allow the model train levitate is flat, as this would make the north (N) pole of the magnets on the train point up and the north (N) poles of the magnets on the track point down.

During a research work, an effective and efficient way to follow the scientific method includes:
Make observations.
Ask questions.
Construct a hypothesis.
Test the hypothesis with an investigation.
Analyze the data.
Explain the result.
Communicate the result.
The scientific method is the variety of techniques that scientists use to observe, examine, investigate, and study the natural world and explain it based on evidence, theories, evidence, hypotheses, or factual information that scientists derive from their research work.
It can be defined as the scientific method usually involves combining traditional scientific processes with critical thinking, scientific knowledge, and reasoning to generate new ideas. Please note that if your hypothes is true, it should be shared with the community. However, if your hypothesis is wrong, you should build another hypothesis and repeat the process.
