Physics Quiz - Magnetism
 1. Magnetic materials are:A only made of ironB made from any metalC iron, nickel and cobalt 2. The small groups of atoms that behave like small magnets inside a large magnet are called:A iron filingsB domainsC poles 3. In unmagnetised steel, the domains:A are aligned in the same directionB are in different directionsC are not present 4. In a magnet, the domains:A are aligned in the same directionB are in different directionsC are not present 5. To demagnetise a magnet, one can:A drop or hit it for a period of timeB heat it for some timeC both of the above 6. The ends of a magnet are called:A fieldsB polesC domains 7. Unlike poles:A attractB have no effect on each otherC repel 8. Like poles:A repelB have no effect on each otherC attract 9. The north pole of a magnet will attract:Athe north pole of a magnetBthe south pole of a magnet and any unmagnetised ironCboth poles of a magnet and any magnetic materials 10. If two south poles are close to each other, they will: Aattract each other Brepel each other Chave no effect on each other 11. Repulsion between a magnet and another object indicates that: Athe other is made of a metal that is non-magnetic Bone has a north pole and the other has a south pole Cthe other object is also a magnet 12. The lines of a magnetic field go from: Anorth pole to south pole Bsouth pole to north pole Cin any direction 13. The magnetic field of a magnet: Ais always as strong anywhere around a magnet Bonly exists on the poles themselves Cweakens as the distance from the magnet increases 14. If pole A of a magnet repels pole B of a second magnet, and pole B attracts pole C of a third magnet, what can be said about pole A and pole C? AA and C are both north poles BA and C are like poles CA and C are unlike poles 15. If a person winds a coil of wire around a steel rod, and then passes an electric current through the wire, then: Athe steel rod becomes an electromagnet Bthe steel rod becomes electrified and should not be touched Cthe wire becomes magnetised
