Current in a Magnetic Field
- Define
- Magnetic Flux Density
- The Tesla
- The Ampere
- The Coulomb
- State
- Fleming's left hand rule
- Unit of magnetic flux density
- The factors on which the size of
the force on a current carrying
conductor in a magnetic field
depends
- Recall that
- A current carrying conductor experiences a
force when placed in a magnetic field
- The direction of the force is perpendicular
to the current and magnetic field
- The size of the force is directly proportional to the
current, length of the conductor and strength of the
magnetic field.
- Current carrying conductors exert
forces on each other due to their
magnetic fields
- A charged particle
moving in a magnetic
field experiences a
force
- A charged particle moving
perpendicular to a
magnetic field moves in a
circle
- Describe an experiment to show:
- The force on a current carrying conductor in a magnetic field
- The forces on a current carrying coil in a magneticfield
- That current carrying conductors exert forces on each other
- The principle on which the definition of the ampere is based
- List
- Three practical applications of
the force on a current carrying
coil in a magnetic field
- Formulae
- F=IlB
- F=qvB
- F = mv^2/r
- Derive
- F=qvB
