Topics in Magnetic Effects of Electric Current

1

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

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

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

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.
