Flashcard 4: What question best checks how distance affects a magnetic interaction?

Answer: What happens when the magnet is moved farther away. Magnetic force weakens as distance increases.

Flashcard 5: What is the word for the force that pushes objects away from each other in electric or magnetic interactions?

Answer: Repulsion. Objects move apart due to electric or magnetic forces.

Flashcard 6: What is a magnetic interaction at a distance?

Answer: A push or pull caused by magnets without touching. Magnets create forces that act through space.

Flashcard 7: What is meant by an interaction at a distance in electricity or magnetism?

Answer: A push or pull that happens without objects touching. Forces can act through empty space without physical contact.

Flashcard 8: What question best checks if changing the magnet orientation changes the interaction?

Answer: What happens when the magnet is flipped around. Flipping reverses poles, changing attract/repel behavior.

Flashcard 9: What question best tests magnetism at a distance: 'Does a magnet pull a nail through air?' or 'Is a nail shiny?'

Flashcard 10: Identify the best question to test magnetism: "Will this object be attracted to a magnet?"

Answer: Test whether the object is magnetic. This question directly checks if something responds to magnets.

Flashcard 11: What question should you ask to check if two magnets will repel before you bring them close?

Answer: Which poles are facing each other. Knowing pole arrangement predicts attract or repel behavior.

Flashcard 12: What are the two pole names found on every magnet?

Answer: North pole and south pole. Every magnet has these two opposite ends.

Flashcard 13: Which question keeps one variable: 'Does a rubbed balloon pull the same paper bits at $2$ cm and $10$ cm?'

Answer: Does a rubbed balloon pull the same paper bits at $2$ cm and $10$ cm. Tests only distance while keeping object constant.

Flashcard 14: What does it mean when an electric force acts "at a distance" between two objects?

Answer: The objects can push or pull without touching. Forces can act through empty space without physical contact.

Flashcard 15: What question best checks how distance affects magnetism: 'Does the pull change when the magnet is farther away?'

Answer: Does the pull change when the magnet is farther away. Tests if magnetic force weakens with distance.

Flashcard 16: What question best tests static electricity at a distance: 'Does a rubbed balloon pull paper bits?' or 'Is paper white?'

Answer: Does a rubbed balloon pull paper bits. Tests if electric charge attracts through empty space.

Flashcard 17: Which observation suggests a magnetic interaction at a distance: a nail moves toward a magnet without contact?

Answer: A nail moves toward a magnet without contact. Movement without touching proves force at distance.

Flashcard 18: What is the best question to ask if a paper clip moves when a magnet is nearby but not touching?

Flashcard 19: Which question best checks strength: "Does a stronger magnet pull from farther away than a weaker magnet?"

Answer: It compares magnetic force strength at different distances. Tests if stronger magnets have longer-range effects.

Flashcard 20: What is the correct term for an object that has an electric charge?

Answer: A charged object. Objects with extra or missing electrons have electric charge.

Flashcard 21: Which question keeps one variable: 'Does a magnet pull the same paper clip at $1$ cm and $5$ cm?'

Answer: Does a magnet pull the same paper clip at $1$ cm and $5$ cm. Tests only distance while keeping object constant.

Flashcard 22: Which option is most likely to be attracted to a magnet: a wooden stick or a steel paper clip?

Answer: A steel paper clip. Steel contains iron, which magnets attract.

Flashcard 23: What question should you ask to check if two charged objects will attract or repel?

Answer: Are their charges the same or different. Charge type determines if objects attract or repel.

Flashcard 24: What question best checks whether a magnet can act through a material like paper or plastic?

Answer: Does it still pull the object with paper or plastic in between. Magnetic fields pass through non-magnetic materials.

Flashcard 25: Choose the best question for a fair test of distance: "Am I keeping the same objects and only changing distance?"

Answer: Yes; change only one variable (distance). Fair tests change only one factor to see its effect.

Flashcard 26: Which option is correct for magnets: do like poles attract or repel each other?

Answer: Like poles repel. Same magnetic poles (N-N or S-S) push away from each other.

Flashcard 27: What does it mean when a magnetic force acts "at a distance" between objects?

Answer: Magnets can push or pull without touching. Magnetic forces work through empty space without contact.

Flashcard 28: What question best tests whether a force is acting at a distance in a magnet setup?

Answer: Does it move without touching. Movement without contact proves a force acts at a distance.

Flashcard 29: Which question best helps you identify the cause when a balloon sticks to a wall after rubbing?

Answer: Did rubbing the balloon create static electricity. Rubbing transfers electrons, creating static charge.

Flashcard 30: Which observation suggests an electric interaction at a distance: small paper bits jump toward a rubbed balloon?

Answer: Paper bits jump toward a rubbed balloon. Movement without touching proves force at distance.

Flashcard 31: What is the name of the region around a magnet where it can exert a force?

Answer: Magnetic field. The invisible area where magnetic force can be felt.

Flashcard 32: What is the name of the region around a magnet where forces can act?

Answer: A magnetic field. The invisible area where magnetic forces can act on objects.

Flashcard 33: Which question best checks distance effects: "Does the pull change when I move the objects farther apart?"

Answer: It tests how force changes with distance. Moving objects apart tests if force weakens with distance.

Flashcard 34: Which option is a fair test question about magnets: 'Does magnet strength change with distance using the same nail?'

Answer: Does magnet strength change with distance using the same nail. Controls variables by changing only distance.

Flashcard 35: What question best checks repulsion with magnets: 'Do two magnet ends push away when brought close?'

Answer: Do two magnet ends push away when brought close. Like poles repel each other without touching.

Flashcard 36: Identify the best question to check for contact force: "Do the objects still move when they do not touch?"

Answer: It tests for a non-contact (distance) force. Movement without touching proves force acts at a distance.

Flashcard 37: Which option is correct for magnets: do opposite poles attract or repel each other?

Answer: Opposite poles attract. Different magnetic poles (N-S) pull toward each other.
