Question

guiding question
what makes a magnet stick to your refrigerator?
phenomenon
examine the video and answer the questions.
1 in this video, a person holds a magnet near a toy car. which of these statements best describes the effect of the magnet on the car?
a the magnet changes the direction of the car by touching it
b the magnet appears to push and pull the car without touching it
c one side of the magnet makes the car move but the other side doesnt
d one side of the magnet makes the car move faster than the other does
2 what causes the car to change direction halfway through the video?
a the magnets strength doubles
b the magnets direction changes

Explanation:

Question 1

To solve this, we analyze each option:

• Option A: The magnet doesn't touch the car, so this is wrong.
• Option B: Magnets exert magnetic force at a distance (push/pull without contact), which matches the video.
• Option C: Both sides of a magnet (poles) can exert force, so this is incorrect.
• Option D: The speed difference isn't the main effect shown; the key is force at a distance.

• Option A: Magnet strength doesn't double suddenly in the video.
• Option B: When the magnet's direction (poles) changes, the magnetic force direction changes, causing the car to reverse direction (since magnetic force direction depends on pole orientation).

Answer:

B. The magnet appears to push and pull the car without touching it

Question 2 (assuming the visible option B is "The magnet’s direction changes")
