Question 1:

The answer is A. Iron because iron is a ferromagnetic material, meaning it is strongly attracted to magnets and can be magnetized itself. The other materials (glass, plastic, and copper) are not magnetic under normal conditions.

Question 2:

The correct row is C:

• North and North pole → repel (like poles repel)

• North and South pole → attract (opposite poles attract)

Question 3:

Let’s check each statement:

I. Magnets can be made using any metal.
False — only certain metals (iron, nickel, cobalt, and some alloys) are ferromagnetic; most metals (e.g., copper, aluminum) cannot be made into permanent magnets.

II. Magnets produce forces on other magnets.
True — magnetic forces act between magnets.

III. Magnetic field lines are drawn with arrows pointing from north to south.
True — by convention, magnetic field lines go from the north pole to the south pole outside the magnet.

So II and III are true.

That means the correct answer is C. II and III.

Question 4:

Magnetic field lines show the direction of the magnetic force that would act on the north pole of a compass needle (or a hypothetical isolated north pole).

That means the correct answer is:

B. The direction the north pole of a compass would point.

Question 5:

The correct answer is A. a permanent magnet.

Permanent magnets are made from materials (like steel) that retain their magnetism for a long time after being magnetized.

• Soft magnets (e.g., iron) are easy to magnetize but lose their magnetism quickly.

• Induced magnets are temporary and only magnetic when in a magnetic field.

Question 6:

The correct answer is A. the Earth has a magnetic field.

Magnetic compasses align with the Earth's magnetic field, with the north pole of the compass pointing toward the geographic North Pole (which is near the Earth’s magnetic south pole, magnetically speaking).

Question 7:

The correct row showing the three results is C.

Reasoning:

1. Steel: Steel is a ferromagnetic material, meaning it is attracted to magnets. Therefore, the result is attract.

2. Copper: Copper is a non-magnetic metal. It will not be picked up or moved by a permanent bar magnet. Therefore, the result is no effect.

3. South Pole: In the diagram, the South (S) pole of the upper magnet is brought near the South (S) pole of the lower magnet. Since like poles repel, the result is repel.

Question 8:

The best description of the relationship between distance and magnetic force is:

B. If the distance between magnets is increased, the force gets weaker.

Magnetic force decreases as distance increases — it follows an inverse-square-like relationship for dipoles.

Question 9: A magnetic field around a bar magnet is strongest where the field lines are close together. This occurs close to the ends of the magnets, shown by letter D.

Question 10:

Magnetic field lines - by convention - are always directed away from north poles and towards south poles. From this definition, both green and blue lines are in the wrong direction.
