What could Eric have changed in his electromagnet that caused the decrease in magnetic force from point A to point B?
(You MUST give at least 3 possible reasons/changes in the electromagnet)

Explanation:

There is not context to know how the electromagnet is built and what the the points A, B, and C represent. Nevertheless, you can conclude from the graph that the force of the electromagnet decreased linearly from the situation A to the situation B.

The strength of the force from an electromagnet depends on:

How those factors can be modified to decrease the magnetic force from point A to point B:

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
