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.

<u>Complete Question:</u>
Jolie builds a model of a maglev train. She uses disc magnets to levitate the train. A disc magnet has its north and south poles on its faces, as shown.
What is the best way to arrange the magnets on the train and on the track so that the model train levitates?
Answer:
The answer is Option A
Explanation:
Cup of milk m = 299 mg
Cup of juice j = 261 mg
Limit of intake = 1000mg
Total amount of calcium from milk = 299 × m = 299m mg
Total amount of calcium from juice = 261 × j = 261j mg
Since it must be equal to or exceeding the daily limit u use the GREATER THAN OR EQUAL TO SIGN.
299m + 261j <u>></u> 1000
Loud sounds would cause the ossicles to move too much, which would cause damage to the inner ear.
Answer:
26 of 40 so you need to multiply 40X65% = 26 so 65% is the answer
