उत्तर
Fleming's left-rule will be used here to find the direction of force experienced by the conductor. According to this rule, when left hand's thumb, forefinger and centre finger are held mutually perpendicular to one another, the forefinger represents the direction of the magnetic field, the centre finger represents the direction of the current and the thumb represents the direction of the force experienced by the coil.
