(d) The direction of the magnetic field can be determined by applying Fleming’s left hand rule. According this rule, if we arrange the thumb, the centre finger, and the forefinger of the left hand at right angles to each other, then the thumb points towards the direction of the magnetic force, the cRead more
(d) The direction of the magnetic field can be determined by applying Fleming’s left hand rule. According this rule, if we arrange the thumb, the centre finger, and the forefinger of the left hand at right angles to each other, then the thumb points towards the direction of the magnetic force, the centre finger gives the direction of current, and the forefinger points in the direction of magnetic field. As the direction of a positively charged alpha particle is towards west, the direction of current will be the same i.e., towards the west. If the direction of magnetic force is towards the north. Hence, according to Fleming’s left hand rule, the direction of the magnetic field will be upwards.
Fleming’s left hand rule states that if we arrange the thumb, the centre finger, and the forefinger of the left hand at right angles to each other, then the thumb points towards the direction of the magnetic force, the centre finger gives the direction of current, and the forefinger points in the diRead more

The principle of an electric motor is based on the magnetic effect of current. A current-carrying loop experiences a force and rotates when placed in a magnetic field. The direction of rotation of the loop is determined by Fleming's left-hand rule.
