Question 1

Which statements describe the characteristics of a magnet? Select four options.A magnet attracts objects containing iron.A magnet attracts objects containing aluminum.A magnet repels other magnets.A magnet attracts other magnets.A magnet aligns with Earth’s south pole.A magnet aligns with Earth’s north pole.

Revolt · Accepted Answer

A magnet attracts objects containing iron.; A magnet repels other magnets.; A magnet attracts other magnets.; A magnet aligns with Earth’s north pole.

Question 2

Which statements best describe magnetic fields? Select three options..A magnetic field is the area around a magnet where a force is exerted on certain objects.A magnetic field is an area of land where magnets are found.Magnetic field lines are strongest around the middle of the magnet. Magnetic field lines spread out of the north end of the magnet.Magnetic fields are three-dimensional and resemble a bubble.

Revolt · Accepted Answer

A magnetic field is the area around a magnet where a force is exerted on certain objects.; Magnetic field lines spread out of the north end of the magnet.; Magnetic fields are three-dimensional and resemble a bubble.

Question 3

If a magnet is broken into two pieces, what happens to the magnetic poles?

Revolt · Accepted Answer

Each piece will still have a north pole and a south pole.

Question 4

Which diagram shows magnets that will attract each other?

Revolt · Accepted Answer

[Image: 2 bar magnets top to bottom with their long axes v...]

Question 5

Maglev trains use magnets on the train and guideway to levitate the train off the track. The north pole of the magnets on the train must face the

Revolt · Accepted Answer

north pole of the magnets on the guideway so they repel.

Question 6

Three magnets are placed on a plastic stick as shown in the image. Explain how the magnets need to be rearranged so that they stick together and why rearranging them this way allows them to stick together.

Revolt · Accepted Answer

To make all three magnets stick together, the top magnet needs to be flipped over. Currently, the top and middle magnets have like poles (South poles) facing each other, which creates a repulsive force that keeps them apart. By flipping the top magnet, its North pole will face the South pole of the middle magnet. Since opposite poles attract, the magnetic force will pull the magnets together, causing them to stick.

Question 10

Why does a compass point toward Earth’s geographic North Pole? Select three options.Earth’s geographic North Pole is close to the magnetic north pole.Earth’s geographic North Pole is close to the magnetic south pole.Magnets allowed to move freely align themselves to point north.The north pole on a compass is attracted to Earth’s magnetic north pole.The north pole on a compass is attracted to Earth’s magnetic south pole.

Revolt · Accepted Answer

Earth’s geographic North Pole is close to the magnetic south pole.; Magnets allowed to move freely align themselves to point north.; The north pole on a compass is attracted to Earth’s magnetic south pole.
