Simple phenomena of magnetism

What the syllabus asks of you

• Describe the forces between magnetic poles 10 Explain that magnetic forces are due to and between magnets and magnetic materials, interactions between magnetic fields including the use of the terms north pole (N pole), south pole (S pole), attraction and repulsion, magnetised and unmagnetised
• Describe induced magnetism
• State the differences between the properties of temporary magnets (made of soft iron) and the properties of permanent magnets (made of steel
• State the difference between magnetic and non-magnetic materials
• Describe a magnetic field as a region in which a magnetic pole experiences a force
• Draw the pattern and direction of magnetic field 11 Know that the relative strength of a magnetic lines around a bar magnet field is represented by the spacing of the magnetic field lines
• State that the direction of a magnetic field at a point is the direction of the force on the N pole of a magnet at that point
• Describe the plotting of magnetic field lines with a compass or iron filings and the use of a compass to determine the direction of the magnetic field
• Describe the uses of permanent magnets and electromagnets
