Answer the following questions for a case in which a current carrying conductor is placed in a uniform magnetic field :
(a)
List three factors on which the magnitude of the force acting on the conductor depends.
(b)
When is the magnitude of force on the conductor maximum ?
(c)
Name the rule which helps in determining the direction of force on the conductor and give its one application.
Marking-scheme solution
(i) Magnitude of current,
(ii) Strength of the magnetic field.
(iii) Orientation of the conductor in the magnetic field.
(iv) Length of the conductor (Any $\displaystyle 3$)
(b) When the current carrying conductor is placed at right angles to (or perpendicular) to the direction of the magnetic field.
(c) Fleming's Left-hand rule Electric motors/Microphones/Generator
