Question

The figure showing Fleming’s left-hand rule is given. Which figure or thumb shows the direction of flow of electric current?

Answer 1

The magnetic field will be characterized by the direction of the fingers, while the current will flow in the direction of the thumb. This means that changing the current's direction likewise changes the magnetic field's direction. An electric current produces a magnetic field that is always perpendicular to the current flow direction. The middle arrow indicates the direction of the current in the conductor (wire). The circles are field lines, and the arrows on the lines show their orientation.

Complete answer:
Fleming's left-hand rule determines the direction of current flow in a current-carrying wire in a magnetic field. The direction of the electric current is indicated by the second finger.

As seen in the figure, a left hand can be used to indicate three mutually orthogonal axes on the thumb, forefinger, and middle finger. When the thumb, center finger, and forefinger of the left hand are arranged at right angles to each other, the thumb points in the direction of the magnetic force, the center finger points in the direction of the current, and the forefinger points in the direction of the current.

A magnetic field's recognized direction is from its north pole to its south pole. Holding the current-carrying conductor in your left hand with your thumb extended in the direction of the electron passage from negative to positive, you can determine this direction.

Note: A current is induced in a wire coil when it is put in a changing magnetic field. Something generates an electric field that drives the charges around the wire, causing current to flow. (It can't be the magnetic force because the charges aren't moving at first.).In this circuit, the current flows in the opposite direction. The right thumb is pointed along the wire pointing to the left at the top of the circuit, using the right-hand rule for conventional current in the wire.
