Magnetism and Electric Current

1. Magnetic field lines are directed from the south pole to the north pole inside the magnet and from the north pole to the south outside the magnet.
2. The direction of a magnetic field produced due to a current-carrying conductor relies upon the same direction in which the current is flowing.
3. The direction of the magnetic field gets reversed if the direction of the electric current changes.
4. The Right-Hand Thumb rule is used to represent the direction of the magnetic field in electric current through a straight conductor.
5. The magnetic field produced in a circular current carrying conductor is the same as that of the magnetic field due to a straight current-carrying conductor.
6. The magnetic field produced by the current-carrying solenoid is similar to a bar magnet.
7. Direct current is the unidirectional flow of electric current.
8. A direct current can be obtained from an alternating current using a rectifier.
9. Direct current power is widely used in low voltage applications such as charging batteries and light aircraft electrical systems.
10. Fleming’s Right Hand Rule and Fleming’s Left Hand Rule are used to determine the direction of the magnetic force, magnetic field, and current.
