How will the force get affected on reversing the direction of current flow?
(i) On reversing the direction of current, the conductor gets deflected in the upward direction. i.e., the direction of conductor reverses. (ii) If the magnitude of current is doubled, it will result in doubling the magnitude of the force.
How do you reverse the direction of force?
The direction of the current must be reversed every half turn, otherwise the coil comes to a halt again. This is achieved using a conducting ring split in two, called a split ring or commutator. A coil of wire is used with lots of turns to increase the effect of the magnetic field.
What happens when direction of magnetic field is reversed without changing the direction of current?
\((a)\) If the direction magnetic field is reversed without changing the direction of current then the force will act in the opposite direction to that of the previous direction. \((c)\) If the direction of both the current and magnetic field is reversed then the force remains in the same direction.
How will the magnetic force get affected on a doubling the magnitude of current B reversing the direction of current flow?
1) doubling the magnitude of current : The magnetic field is directly proportional to the magnitude of current, and the force experienced is directly proportional to the magnetic field. Reversing the direction of current will reverse the direction of magnetic field which in turn reverse the direction of force.
Why does a current carrying conductor kept in a magnetic field experience force?
A current carrying conductor kept in a magnetic field experience force because a magnetic field is produced by an electric current that flows through a conductor. This magnetic field exerts a force that is equal in magnitude and opposite in direction.
What would be the direction of force experienced by a conductor in which current is flowing from west to east?
1 Answer. The direction of earth’s magnetic field is from G-south to G-north. Let current is from west to east. Therefore force is vertically upwards.
Will an induced current flow through a conductor pointing east west when it is rapidly moved towards west into a magnetic field pointing towards South?
Hence, in this case, as the thumb points from east to west the fingers at a point above will point in the north direction. Hence, a direction of a magnetic field will be towards the north.
When the current through the straight conductor be doubled then magnetic field becomes?
So when current I is doubled, the force will be doubled.
How can one determine the direction of force on a straight current carrying conductor placed inside a magnetic field?
The Fleming’s left hand rule can be used to determine the direction of the force, magnetic field and current. A left hand can be held, so that the thumb, first finger and second finger are held mutually perpendicular to each other. The thumb represents the direction of Motion resulting from the force on the conductor.
Which rule is used to find the direction of force in current carrying conductor?
(ii) Fleming’s left-hand rule: Force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it.
What is the direction of force acting on the conductor?
If an upward force is applied to a conductor, conventional current flows from right to left. On the corollary, is (conventional) current passes in the direction left to right without moving the conductor, the force on the conductor acts upward.
Why no force acts on a current carrying conductor when it is parallel to the magnetic field?
Answer: No force acts on a current carrying conductor when it is placed parallel to the magnetic field. For example:- You can see in a DC motor, the coil which is parallel to the magnetic field lines does not experience a force, but the coil which is perpendicular to the magnetic field lines experiences.
