**Understanding the force on a current-carrying conductor in a magnetic field
**
**What happens to a current-carrying conductor in a magnetic field.Pattern of the combined magnetic field due to current carrying conductor in a magnetic field.How a current carrying conductor in a magnetic field experiences a force.The factors that affect the magnitude of the force on a current-carrying conductor in a magnetic field.How a current carrying coil in a magnetic field experiences a turning force.How a direct current motor works.Factors that affect the speed of rotation of an electric motor
**
**When a current-carrying conductor is placed in a magnetic field,
There is an interaction between the magnetic field produced by the current and the permanent magnetic field,
which leads to a force being experienced by the conductor.
**External magnetic field Magnetic field due to currentCatapult field
**The resulting magnetic field is stronger on one side of conductorTherefore, a resultant magnetic force acts on the conductor
**
**How determine the direction of force acts on the conductor ?force
**Mark and label with I for current direction at copper rodMark and label with F for direction of moving copper rodMark and label with I for current direction at copper rodMark and label with F for direction of moving copper rodMark and label with I for current direction at copper rod.Mark and label with F for direction of moving copper rod.
