Name:

Pre-lab Questions: (9 points)
Explain what it means when we say a substance is magnetic.

Discuss the relationship between electric and magnetic fields.

Which type of wires (copper, aluminum, or string) are ferromagnetic metals?

String

Lab Activity
Interact with the virtual laboratory to create an electromagnet to pick up paperclips. Notice that there are many variables to test in this lab:
different types of material,
different gauges or thicknesses of wire,
number of winds around the iron bar,
the voltage

→ Open the lab interactive and run a few trials changing the variables each time. Decide which variable you want to change in order to make a strong electromagnet and record it here.

Hypothesis (5 points)
Record your hypothesis as an “if, then” statement.
(If the independent variable does this, then the dependent variable will do that….)

Variables (6 points)
Independent Variable:

Dependent Variable:

Controlled Variables:

Procedure
Use the virtual laboratory to create an electromagnet, changing only your independent variable.
Record the data and what each variable was set at for each trial.
Record the number of paper clips the electromagnet picked up for each trial
Repeat your trial three times. You should vary only the independent variable you chose.

Data (10 points)
Record your data for each trial.

Trial
Size of Wire Gauge
Material of Wire
Voltage
Number of Winds
Resulting Paper Clips Picked Up
Trial 1

Trial 2

Trial 3

Post-Lab Questions
Review your data. Did your experiment support your hypothesis? Explain your answer. (3 points)

What role does voltage play in the formation or use of an electromagnet? (3 points)

If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet? (2 points)

What is an advantage of using an electromagnet rather than a regular magnet? (2 points)

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
