Key Topics to Revise
1
Oersted's Discovery and Magnetic Field Around Current-Carrying Conductor
- Hans Christian Oersted (1820) discovered that a current-carrying conductor produces a magnetic field around it
- A magnetic compass deflects when brought near a current-carrying wire, proving the existence of magnetic field
- The direction of magnetic field depends on the direction of current flow
2
Magnetic Field Around Circular Loop and Solenoid
- For a circular loop: magnetic field lines are circular near the wire, straight through the center
- At the center of circular loop, all field lines point in the same direction
- If current is clockwise (viewed from one side), magnetic field goes into the loop from that side
3
Factors Affecting Strength of Magnetic Field
- Magnetic field strength increases with increase in current through the conductor
- Increasing number of turns in a coil increases magnetic field strength
- Using soft iron core inside solenoid greatly increases magnetic field strength
4
Force on Current-Carrying Conductor in Magnetic Field
- A current-carrying conductor experiences force when placed in a magnetic field
- The force is maximum when conductor is perpendicular to magnetic field
- Force direction depends on both current direction and magnetic field direction
