Key Topics to Revise
1. Magnetic field and magnetic field lines
- A magnetic field is the region around a magnet where its force can be detected.
- A compass needle is a small bar magnet with a north-seeking end and a south-seeking end.
- Like poles repel and unlike poles attract.
2. Magnetic field due to current-carrying conductors
- An electric current-carrying wire behaves like a magnet and deflects a compass needle.
- The direction of magnetic field changes when the direction of current is reversed.
- For a straight current-carrying wire, the magnetic field lines are concentric circles around the wire.
3. Force on a current-carrying conductor in a magnetic field
- A current-carrying conductor placed in a magnetic field experiences a force.
- The force is greatest when current direction is at right angles to the magnetic field.
- The direction of force changes if the direction of current changes.
4. Magnetism in medicine
- Weak ion currents along nerve cells produce magnetic fields.
- The heart and brain are the two main organs where the magnetic field produced is significant.
- These fields are very weak and are about one-billionth of the earth's magnetic field.
