Simple phenomena of magnetism outcomes11 objectives
- Explain the interactions between magnetic poles and between magnets and magnetic materials, using terms like north pole, south pole, attraction, repulsion, magnetised, and unmagnetised.
- Explain the concept of induced magnetism.
- Identify the differences in properties between temporary magnets made of soft iron and permanent magnets made of steel.
- Differentiate between magnetic and non-magnetic materials.
- Define a magnetic field as an area where a magnetic pole experiences a force.
- Illustrate the pattern and direction of magnetic field lines surrounding a bar magnet.
- Indicate that the direction of a magnetic field at a specific point is the direction of the force acting on the north pole of a magnet at that location.
- Explain how to plot magnetic field lines using a compass or iron filings, and how to use a compass to find the direction of the magnetic field.
- Discuss the applications of permanent magnets and electromagnets.
- Clarify that magnetic forces arise from interactions between magnetic fields.
- Recognize that the strength of a magnetic field is indicated by the spacing of the magnetic field lines.
