Multiple choice questions

Multiple choice questions are perhaps the easiest to complete, you simply put a cross in a box. However, the questions often have two answers that could, at first glance, be correct. Don’t make the mistake of reading the first answer and thinking it is correct without checking all the others.

If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes, you will get zero marks. These multiple choice questions will not start with command words like ‘describe’ or ‘explain’. They will be written in the form of a question like ‘What…?’ or ‘Why…?’.

There will be more multiple choice questions on the Foundation paper.

Sample question 1 - Foundation

Question

The Earth has a magnetic field.

What causes the Earth’s magnetic field? [1 mark]

Tick one box.

AThe movement of liquid iron in the Earth’s outer core.
BThe gravitational field of the Earth.
CThe permanent magnet in the Earth’s core.
AThe movement of liquid iron in the Earth’s outer core.
BThe gravitational field of the Earth.
CThe permanent magnet in the Earth’s core.

The Earth does not contain a permanent magnet. Its magnetic field is produced by the movement between the inner and outer cores.

Sample question 2 - Foundation

Question

Which two materials are magnetic? [2 marks]

Tick two boxes.

ACarbon
BCobalt
CCopper
DNickel
ESodium
ACarbon
BCobalt
CCopper
DNickel
ESodium

The magnetic elements are: iron, nickel and cobalt. Alloy steel is also magnetic because it is mostly iron.

Sample question 3 - Higher

Question

Why is iron a suitable material for the core of a transformer? [1 mark]

Tick one box.

AIt is a metal
BIt will not get hot
CIt is easily magnetised
DIt is an electrical conductor
AIt is a metal
BIt will not get hot
CIt is easily magnetised
DIt is an electrical conductor

Although the other answers may give some properties of iron, it is best to use iron in a transformer because it is easily magnetised. This allows it to direct the alternating magnetic field between the coils.
