You can think of a magnet<span> as a bundle of tiny </span>magnets<span>, </span><span> that are jammed together. Each one reinforces the </span>magnetic<span> fields of the others. Each one has a tiny north and south pole. </span>If you cut<span> one in </span>half<span>, the newly </span>cut<span> faces will become the new north or south poles of the smaller pieces.

So the answer is D
Answer:
True, people would actually pray to Poseidon for safe sea travel
Answer:
B'= 3.333 B
Explanation:
Lets take
Initial area = A
Magnetic field = B
The area after compression
A'=0.3 A
Magnetic field = B'
We know that flux ,Ф
Ф = B A
Given that flux is constant so
B A = B' A'
B A=B' x 0.3 A
B'= 3.333 B
It means that magnetic field will increase.
A scientific theory is supported by evidence, can evolve over time, and is true all the time.
Scientific theories are NOT guesses but rather they are statements that are PROVEN correct through research, examination, and testing. Scientific theories can evolve as well, like Newton's laws change, and they are true all the time because they are called theories, theories are FACTS, definition of fact means true statement, not an opinion but rather fact, only hypothesis are not true all the time and opinions and guesses and etc that haven't been tested and confirmed.
