Magnetic Fields - Part 2

Standard PS2.2 - Conduct an investigation to provide evidence that fields exist between objects exerting forces on each other even through the objects are not in contact.

Learning Intention​

Forces can cause objects to vibrate, move without touching each other.​

​

Success Criteria​

I can create identify magnetic and nonmagnetic materials​

​

I can create models of a magnetic field.

I can use a magnet and a coil to explain interactions.

​Watch the first 2:30.

Multiple Choice

What happens when two like poles are brought near each other?

• They attract (pull) each other.

• They repel (push) each other.

• They do not interact.

• They align and become a single magnet.

Multiple Choice

Which of the following is true about the magnetic poles of a magnet?

• Every magnet has a pole.

• Opposite poles repel each other.

• Like poles attract each other.

• Every magnet has two poles- a north and a south.

Multiple Choice

Which test objects were magnetic?

• paperclip, penny, and coil

• paperclip, quarter, and penny

• aluminum foil, paperclip, and compass

• paperclip, compass, and nail

Multiple Select

Which of the following statements correctly distinguishes between Earth's magnetic poles and geographic poles? Choose 2 answers.

• The geographic poles are fixed locations, while the magnetic poles shift over time due to changes in Earth's core.

• The magnetic poles are located exactly at the same points as the geographic poles.

• The geographic poles are determined by Earth's magnetic field, while the magnetic poles are fixed locations on the surface of the Earth.

• The magnetic north pole is near the geographic south pole. The magnetic south pole is near the geographic north pole.

Multiple Select

What can determine the strength of a magnet? Choose all that apply.

• Size and shape

• How aligned the domains are

• The color

• The type of material it is made from

Multiple Choice

What happens if you cut a magnet in half?

• You would create a single stronger magnet on one side.

• Each half would become a magnet with its own north and south poles.

• The magnetic field would disappear.

• The domains would not be aligned and would scatter randomly.

Multiple Choice

Describe the flow the magnetic force in a magnetic and between magnets.

• from north into north

• from south into south

• from south into north

• from north into south

Multiple Choice

The strength of the magnetic force between two magnets depends on which of the following factors?

• The temperature of the magnets.

• The distance between the two magnets.

• The material from which the magnets are made.

• if the poles are put together like or unlike

Multiple Choice

If two magnets are placed at equal distances from each other, but one magnet is stronger than the other, how will the interaction change?

• The stronger magnet will attract the weaker magnet with a stronger force.

• The weaker magnet will attract the stronger magnet with a stronger force.

• Both magnets will repel each other equally.

• The magnets will cancel each other other and have not effect on each other.

Multiple Choice

Which of the following best describes how the magnetic field lines behave between two opposite poles of magnets?

• The magnetic field lines point outward from both poles.

• The magnetic field lines form closed loops between the poles.

• The magnetic field lines do not connect the poles.

• The magnetic field lines point inward at both poles.
