The force on a current carrying conductor in a magnetic field is greatest when the
conductor makes an angle of 60° with the field
force is independent of the angles between the fields and the conductor
conductor is parallel with the field
conductor is at right angle with the field
설명
The force on a current carrying conductor in a magnetic field is greatest when the conductor lies perpendicular in the magnetic field
