2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 43 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

What to Focus On

  • Lodestone is a natural magnet and is Fe3O4.
  • Magnetism is the attraction of iron particles towards lodestone.
  • A freely suspended magnet rests in the north-south direction.
  • Magnetic field is the region around a magnet where magnetic force acts.
  • Torque makes a magnetic needle rotate and settle in one direction.
  • Magnetic lines show field direction.
  • Current in a wire produces a magnetic field around it.
  • Oersted observed this effect in 1820.
  • Greater current gives greater magnetic effect.

Common Mistakes to Avoid

A freely suspended magnet points toward Earth's geographic north pole, so magnetic north and geographic north are the same.

Electromagnets are permanent magnets because they also attract iron.

A solenoid becomes a strong magnet even without a current or without a soft iron core.

Memory Tips

Oersted discovered that current produces a magnetic field around a wire

Magnetic field lines go from north to south and never intersect

Earth behaves like a giant magnet with tilted magnetic poles

Freely suspended magnet points north-south
