PSLE Science: Understanding Magnets

What was the initial setup of the experiment involving magnet X?

• Magnet X was placed on a table.

• Magnet X was hung from a spring.

• Magnet X was placed inside a box.

• Magnet X was submerged in water.

What conclusion can be drawn about object F when it was placed under magnet X?

• Object F is an electrical conductor.

• Object F is a magnet.

• Object F is a magnetic material.

• Object F is a non-magnetic material.

Why did the spring remain at 5 cm when object F was placed under magnet X?

• Because there was no interaction between object F and magnet X.

• Because object F attracted magnet X.

• Because object F was too heavy.

• Because object F repelled magnet X.

What happened to the spring when object G was placed under magnet X?

• The spring became shorter.

• The spring became longer.

• The spring broke.

• The spring remained the same length.

What can be concluded about object G based on its interaction with magnet X?

• Object G is definitely a magnet.

• Object G could be either a magnetic material or a magnet.

• Object G is definitely a non-magnetic material.

• Object G is an electrical insulator.

Why is it important to understand the properties of materials in the context of this experiment?

• To determine the weight of the objects.

• To understand how magnets interact with different materials.

• To measure the length of the spring accurately.

• To calculate the speed of the magnet.

What was observed when object H was placed under magnet X?

• The spring remained the same length.

• The spring became longer.

• The spring disappeared.

• The spring became shorter.

What conclusion can be drawn about object H based on its interaction with magnet X?

• Object H is a non-magnetic material.

• Object H is a magnetic material.

• Object H is a magnet.

• Object H is an electrical conductor.

Why did magnet X move upwards when object H was placed underneath?

• Because object H was too light.

• Because object H attracted magnet X.

• Because object H repelled magnet X.

• Because object H was too heavy.

What type of poles were likely facing each other when object H repelled magnet X?

• East and West poles.

• Like poles.

• Unlike poles.

• North and South poles.
