A student places a straight horizontal conductor in a uniform magnetic field in her laboratory experiment.
a. (i) Define magnetic field lines.
b. (ii) State Fleming’s left-hand rule for finding the direction of the force on a current-carrying conductor in a magnetic field.
c. (iii) The conductor carries a current of 3A and is placed exactly parallel to a uniform magnetic field of 0.5T. Will the conductor experience any force? Give a reason for your answer.
