10th Class Science Magnetic Effects of Electric Current Question Bank Magnetic Effects of Electric Current

  • question_answer
    A current carrying conductor experiences a maximum force in a magnetic field when it is placed

    A) parallel to the field.

    B) perpendicular to the field.

    C) at an angle of \[\text{45}{}^\circ \] to the field.

    D) at an angle of \[\text{6}0{}^\circ \] to the field.

    Correct Answer: B

    Solution :

    \[\theta ={{90}^{o}},\sin \theta =1,\] \[\therefore \] \[F=BIl\] Maximum force is experienced by a conductor when it is placed perpendicular to a magnetic field.
