Section C: Give a short answer to the question given below.
32. (a) (i) A straight cylindrical conductor is suspended with its axis perpendicular to the magnetic field of a horse-shoe magnet. The conductor gets displaced towards left when a current is passed through it. What will happen to the displacement of the conductor if the
(1) current through it is increased?
(2) horse-shoe magnet is replaced by another stronger horse-shoe magnet?
(3) direction of current through it is reversed?
(ii) Name and state the rule for determining the direction of force on a current carrying conductor in a magnetic field.
(1) current through it is increased?
(2) horse-shoe magnet is replaced by another stronger horse-shoe magnet?
(3) direction of current through it is reversed?
(ii) Name and state the rule for determining the direction of force on a current carrying conductor in a magnetic field.
(i) (1) The displacement of conductor will with the increase in current.
(2) The displacement of conductor will with the increase in magnetic strength.
(3) If the direction of current flowing through the conductor is reversed, its direction of displacement will .
(2) The displacement of conductor will with the increase in magnetic strength.
(3) If the direction of current flowing through the conductor is reversed, its direction of displacement will .
(ii) The gives the direction of force experienced by current carrying conductor placed in an external magnetic field.
According to this rule, stretch the thumb, index finger and middle finger of your left hand such that they are mutually perpendicular. If the index finger points in the and the middle finger in the , then the thumb will point in the .
