Study the diagram.
During an experiment, Carol used a bar magnet to stroke Object X repeatedly for 30 times. After that, Object X was able to attract some paper clips. Based on the above experiment, which of the following statements is correct?
Object X is a magnetic metal.
Object X is a non-magnetic metal.
The magnet lost all its magnetism after it was used to stroke Object X.
The more times Object X was stroked, the less number of paper clips it could attract.
Jade attached a magnet on the roof of each toy car as shown in the diagram.
When Jade brought toy car A nearer to toy car B, both toy cars A and B came towards each other. Why is it so?
Toy car A has North pole facing the South pole on Toy car B. Unlike poles attract and the toy cars move towards each other.
Toy car A has North pole facing the North pole on Toy car B. Like poles attract and the toy cars move towards each other.
Toy car A has South pole facing the South pole on Toy car B. Unlike poles attract and the toy cars move towards each other.
Toy car A has North pole facing the North pole on Toy car B. Unlike poles attract and the toy cars move towards each other.
Jade attached a magnet on the roof of each toy car as shown in the diagram.
When Jade brought toy car A nearer to toy car B, both toy cars A and B came towards each other.
Jade then rearranged the magnets and the two toy cars moved away from each other. What did Jade do to make this happen?
Jade reversed Toy car B so that it has North pole facing the North pole on Toy car A. Like poles repel and the toy cars move away from each other.
Jade reversed Toy car A so that it has South pole facing the North pole on Toy car B. Unlike poles repel and the toy cars move away from each other.
Jade reversed Toy car B so that it has North pole facing the South pole on Toy car B. Like poles repel and the toy cars move away from each other.
Jade reversed Toy car B so that it has North pole facing the North pole on Toy car A. Like poles attract and the toy cars move away from each other.

Both metal bars A and B are magnets.
Both metal bars A and B are made of non-magnetic materials.
Metal bar A is a magnet while metal bar B is made of magnetic material.
Metal bar A is made of magnetic material while metal bar B is a magnet.
Shane turned 4 identical iron nails E, F, G and H, into electromagnets using the electrical method as shown in the diagram.
Which one of the following correctly identifies the strongest and weakest electromagnets?
Strongest electromagnet – G, Weakest electromagnet – E
Strongest electromagnet – H, Weakest electromagnet – G
Strongest electromagnet – F, Weakest electromagnet – H
Strongest electromagnet – H, Weakest electromagnet – E
Janet had two identical magnets, A and B, which attracted the same number of steel paper clips. She then dropped magnet A on the floor 300 times.
What would she likely observe of she brought magnets A and B near the same steel paper clips as shown above?
Magnet A attracted more steel paper clips than magnet B.
Magnet A attracted less steel paper clips than magnet B.
Both magnets A and B did not attract any steel paper clips.
Both magnets A and B attracted the same number of steel paper clips.
Which one of the following objects make use of magnets in order to function?
Door stopper
Tap
Zipper
Light bulb
