The student's observations best demonstrate that "The electromagnet's magnetic field is stronger when close to it than far from it." This conclusion can be drawn from the observations, where less force is required to hold the electromagnet at a distance of 20 inches and more force is required as the distance decreases to 10 inches and then to 5 inches, indicating that the magnetic field strength increases as you get closer to the electromagnet.
Use the student’s observations below to any the following question:
Observations
20 inches: no force required
10 inches: small force required; easy to hold in place
5 inches: large force required; very difficult to hold in place
What do the student's observations demonstrate?
