Multiple Choice Questions
1A naturally occurring magnet is called:
(a) Lodestone
(b) Limestone
(c) Sandstone
(d) Coal
(a) is correct
Lodestone is naturally magnetised magnetite.
2Which material is attracted by a magnet?
(a) Wood
(b) Plastic
(c) Glass
(d) Iron
(d) is correct
Iron is a magnetic material.
3Which is generally non-magnetic?
(a) Nickel
(b) Cobalt
(c) Rubber
(d) Iron
(c) is correct
Rubber is not appreciably attracted by an ordinary magnet.
4The magnetic force of a bar magnet is strongest near its:
(a) Entire length equally
(b) Poles
(c) Centre
(d) Painted label
(b) is correct
Iron filings cluster most densely near the two ends.
5Every magnet has:
(a) A north pole and a south pole
(b) Only a north pole
(c) Only a south pole
(d) No poles
(a) is correct
Magnetic poles always occur in pairs.
6If a bar magnet is cut into two pieces, each piece becomes:
(a) Only a north pole
(b) Only a south pole
(c) Non-magnetic in every case
(d) A smaller magnet with two poles
(d) is correct
Cutting does not isolate a single magnetic pole.
7A freely suspended bar magnet settles approximately along the:
(a) Vertical direction
(b) Direction of nearby sunlight
(c) North-south direction
(d) East-west direction
(c) is correct
It aligns with Earth's magnetic field.
8The end of a freely suspended magnet pointing north is its:
(a) Non-magnetic end
(b) North-seeking pole
(c) South pole only
(d) Centre
(b) is correct
This end is labelled N.
9A magnetic compass is used to:
(a) Find directions
(b) Measure temperature
(c) Test food
(d) Measure length
(a) is correct
Its magnetised needle aligns north-south.
10Like poles of two magnets:
(a) Attract
(b) Show no interaction
(c) Always stick permanently
(d) Repel
(d) is correct
North repels north, and south repels south.
11Unlike poles of two magnets:
(a) Lose magnetism
(b) Produce light
(c) Attract
(d) Repel
(c) is correct
A north pole and south pole pull toward each other.
12Which interaction is the sure test of magnetism?
(a) Shine
(b) Repulsion
(c) Attraction only
(d) Weight
(b) is correct
A magnet can attract unmagnetised iron, but repulsion occurs only between like magnetic poles.
13To identify the north pole of an unmarked magnet without another magnet, you can:
(a) Suspend it freely and observe which end points north
(b) Heat it strongly
(c) Drop it in water
(d) Measure its length
(a) is correct
Earth's field provides the directional reference.
14A steel needle can be magnetised by:
(a) Rubbing randomly back and forth
(b) Washing it
(c) Painting it
(d) Stroking it repeatedly in one direction with a magnet
(d) is correct
Repeated one-way strokes align magnetic regions.
15Why might a mechanic magnetise a screwdriver?
(a) To measure voltage
(b) To prevent all rust
(c) To hold steel screws at its tip
(d) To make it lighter
(c) is correct
The magnetic tip attracts small ferromagnetic screws.
16Two ring magnets can appear to float apart when:
(a) Gravity disappears
(b) Like poles face each other
(c) Unlike poles face each other
(d) Both are non-magnetic
(b) is correct
Repulsion between facing like poles prevents contact.
17To bring two repelling ring magnets together without pushing, you can:
(a) Turn one magnet over
(b) Add another like pole between them
(c) Remove the support only
(d) Cool both to room temperature
(a) is correct
Reversing one magnet makes unlike poles face and attract.
18Magnets are made in different shapes mainly to:
(a) Change the rule of poles
(b) Create a single pole
(c) Remove magnetic force
(d) Suit different uses
(d) is correct
Bar, ring, disc and horseshoe designs fit different devices.
19Which action may weaken a magnet?
(a) Using a keeper
(b) Keeping it dry
(c) Heating or hammering it
(d) Storing it carefully
(c) is correct
Heat and mechanical shocks can disturb magnetic alignment.
