THE PHYSICS CAFE                                                               CHAPTER THIRTEEN – MAGNETIC EFFECTS OF ELECTRIC CURRENT 13.03 Force on current carrying conductor in magnetic field and electric motor If a wire carrying current is placed in magnetic field, then Current carrying wire will produce its own magnetic field around it and another magnetic field is already given, so both magnetic field will interact with each other and apply a force on each other, so we can say when a wire carrying current is placed in magnetic field, it experience a force   Hint: Now it become interesting to find out the direction of this force – direction of force is given by ‘Fleming’s left hand rule’ Fleming’s left hand rule: Arrange mutually perpendicular; first and second fi...
