(i) The force experienced by the conductor increases as the current is increased

A student while studying the force experienced by a current cariying conductor in a magnetic field records the following observations:
(i) The force experienced by the conductor increases as the current is increased.
(ii) The force experienced by the conductor decreases as the strength of the magnetic field is increased.
Which of the two observations is correct and why?

Force experience by a current carrying conductor in a magnetic field is given by
F = B I l, where B is magnetic field, I is current and l is the length of the conductor. Observation

  1. is correct because F increases with increase in I. However, observation
  2. is incorrect because F increases with increase in B.
