4. A magnetic compass points North. This shows that...

  • A). the Earth is tilted on its axis.
  • B). the Earth is spinning.
  • C). the Earth has a magnetic field.
  • D). the Earth has gravity.

5. A magnetic field line shows the direction of force acting on

  • A). a magnetic north pole.
  • B). a magnetic south pole.
  • C). a bar magnet.
  • D). a current carrying wire.

6. Which of these diagrams shows the magnetic field line pattern (red lines) around a single straght wire carrying a current?

Magnetic field

7. A student cariies out some experiments to see which variables affect the strength of the field near to the wire above. They change one variable at a time, keeping the others contstant. Only 2 of the experiments gave a result.

Which 2 variables were found to affect the field strength?

  • A). Distance from the wire, thickness of the wire.
  • B). Thickness of the wire, type of metal used.
  • C). Type of metal used, current in the wire.
  • D). Current in the wire, distance from the wire.

 

8. What is the name of a long (empty) coil of wire used to produce a magnetic field?

  • A). A transformer
  • B). A potentiometer
  • C). A solenoid
  • D). An alternator

9. If an iron bar is placed in the middle of this coil, a strong electromagnet is produced. The magnetic field can then be turned on and off.

This type of magnet is ...

  • A). a permanent magnet.
  • B). an induced magnet.
  • C). a Fleming magnet.
  • D). a motor effect magnet.

10. Fleming's Left hand Rule can be used to predict the direction of the force on a wire carrying a current, when placed in a magnetic field.

Which of these correctly identifies the fingers/thumb?

  Force on wire current in wire Magnetic Field direction
A thumb first finger second finger
B thumb second finger first finger
C second finger first finger thumb
D first finger thumb second finger
