Cause of Lorentz Force

Answer. Answer: The expression of magnetic force id defined as F = CIL Sin theta. (a) Hence, as the current, I in the conductor increases, the force also increases.

The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the right hand point in the direction of v, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.

1. F = qvB*sinθ
2. Note: The direction of the magnetic field B is defined as from N to S. Also, the direction of the electrical charge is from (+) to (−).
3. F = BIL.
4. Note: Remember that the convention for current direction in the wire is opposite the direction of the motion of the electrons.

Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. In an electric motor, the electric current and magnetic field exist (which are the causes), and they lead to the force that creates the motion (which is the effect), and so the left-hand rule is used.

The second right hand rule deals with the magnetic field that is induced by current moving through a wire. Take your right hand, and wrap your fingers around the wire, with your thumb pointing in the direction that the current is flowing. Your fingers now represent the direction of the lines of magnetic force!

The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. Therefore if the direction of rotation is know the fingers can be curled in this orientation and the thumb will point in the positive direction, and vice versa. …

Answer. The right-hand screw rule gives the direction of the magnetic field developed by an electric current in a length of wire. The right-hand screw rule gives the direction of the magnetic field developed by an electric current in a length of wire.

The Maxwell’s right hand thumb rule states that ‘When the conductor is held in your right hand, such that the direction of the thumb points the direction of the current and the curled finger gives the direction of the magnetic finger.

Thumb points in the direction of the velocity and fingers point in the direction of the magnetic field, palm points in the direction of the force. From the above definition of screw rule and right hand rule, it is clear that Screw Rule is analogous to Right hand thumb Rule.

Ramsay demonstrates the “three-finger rule” for chopping, with the knuckle of the middle finger forward, protecting the ring and index finger, which are positioned further back.

Maxwell’s Left Hand Rule: By wrapping the left hand fingers around a wire with the thumb pointing in the direction of electron flow (- to +), the fingers will show the direction of the magnetic field travel. The direction of the magnetic field is shown by the direction of the left hand fingers.

The right-hand screw rule, also known as corkscrew rule, associates the direction of an electric current with the direction of the magnetic force lines circling the current, see Ampère’s law. The corkscrew rule is depicted in the figure, where the corkscrew is rotated downward into the cork.

According to Maxwell’s corkscrew in the direction of current, then the direction in which we turn its handle is the direction of magnetic field. This rule is used to determine the direction of magnetic field around a straight-current carrying conductor. Answer verified by Toppr.

Maxwell’s corkscrew rule This rule is also known as the Right hand thumb rule and Right hand grip rule.

Maxwell screws rule : if a righ handed cork screw is assumed to be held along the conductor, direction of magnetic field is same as that of the rotation of screw. is also known as Maxwell corkscrew rule.

A corkscrew is a tool for drawing corks from wine bottles and other household bottles that may be sealed with corks. In its traditional form, a corkscrew simply consists of a pointed metallic helix (often called the “worm”) attached to a handle, which the user screws into the cork and pulls to extract it.

Yes, Maxwell’s corkscrew rule is also called as maxwell’s right hand thumb rule..
