A student was investigating the question: How is the force between electromagnet 1 and 2 affected by distance? They conducted an experiment measuring the force between two electromagnets as distance changed and recorded their data below.

Choose the claim for the student's question:

The greatest force measured (90 N) occurs when the electromagnets are closest (1 meter apart).

When we compare the measurements at different distance, we can see that there is distinct decline in force as distance increases. Because of this and the fact that we know that electromagnetic fields have a limited range of influence, it makes sense to conclude that increasing distance between two electromagnets will decrease the force measured between them.

The force at 1 meter is 90 N while the force at 2.5 meters is 14.4 N.

As distance increases, the force between the two magnets decreases.

Choose all evidence statements for the student's question. (There are three.)

When we compare the measurements at different distance, we can see that there is distinct decline in force as distance increases. Because of this and the fact that we know that electromagnetic fields have a limited range of influence, it makes sense to conclude that increasing distance between two electromagnets will decrease the force measured between them.

The greatest force measured (90 N) occurs when the electromagnets are closest (1 meter apart).

The force at 1 meter is 90 N while the force at 2.5 meters is 14.4 N.

As distance increases, the force between the two magnets decreases.

The weakest force measured (.9 N) occurs when the electromagnets are the farthest apart (10 m apart).
