Permanent and induced magnetism, magnetic forces and fields common mistakes

Common mistakes

• generator-effect induction: avoid permanent and induced magnets

  Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

  Fix itInstead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a student comparing motor and generator effects and the objective to describe how a compass needle points in the direction of the Earth's magnetic field.

• generator-effect induction: avoid permanent and induced magnets

  Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

  Fix itInstead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a calculation using primary and secondary coils and the objective to describe how to plot the magnetic field pattern of a magnet using a compass.

• generator-effect induction: avoid permanent and induced magnets

  Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

  Fix itInstead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a bar magnet and plotting compass practical and the objective to draw the magnetic field pattern of a bar magnet showing how strength and direction change from one point to another.

• generator-effect induction: avoid permanent and induced magnets

  Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

  Fix itInstead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a steel core electromagnet demonstration and the objective to explain how the behaviour of a magnetic compass is evidence that the core of the Earth must be magnetic.

• generator-effect induction: avoid permanent and induced magnets

  Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.

  Fix itInstead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a current-carrying wire between magnetic poles and the objective to apply WS 2.2 when using diagrams to represent magnetic field patterns.
