Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?

∙ 11y ago
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@
So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction.
Ok now why does a force exist on the current carrying conductor?
As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.

In a current carrying conductor what exist around it?
a magnetic field
When is the force experienced by a current carrying conductor placed in a magnetic field the largest?
When the conductor,magnetic field and motion are perpendicular to each other
Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.
Does a current carrying conductor experience a force when kept parallel to the magnetic field?
Yes. The force attracts the conductor to the magnetic field, F= eVB = e(-V.B + VxB) = e[-V.B, ] =- eV.B when V and B are parallel!
What Created around a conductor when electrons flow through that conductor?
Whenever a charge passes through a conductor, a magnetic field is produced. Hence, whenever a current carrying conductor is placed in a magnetic filed, it will experience a force whose direction is determined by Fleming's left hand rule.
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
Why does current carrying conductor experience force when kept near a magnet?
The current carrying conductor has a magnetic field of of its own so when it comes in contact with with another magnetic field it experiences a force which is given by fleming's left hand rule.The force depends upon :direction and the strength of the magnetic fielddirection and the strenth of the current
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
What is difference between d.c genrator and motor?
GENERATOR:converts mechanical energy to electrical energy.It works on flemings right hand rule.It works on the princple that an EMF is induced when a changing magnetic field links with the conductor. This emf is directly proportional to the rate of change of magnetic field linking the conductor.MOTOR:converts electrical energy to mechanical energy.works on flemings left hand rule.It works on the princple that a mechanical force is experienced by the current carrying conductor when placed in magnetic field.
In a current carrying conductor what exist around it?
a magnetic field
When is the force experienced by a current carrying conductor placed in a magnetic field the largest?
When the conductor,magnetic field and motion are perpendicular to each other
Name two devices which use current carrying conductor and magnetic field?
One device for increasing the magnetic field surrounding a current carrying wire, is to wrap the conductor into a set of co-axial coils. A second device is to include a ferromagnetic material in the core of such a coil.
What is the Flemings left hand rule?
The direction of force produced on a current-carrying conductor placed in a magnetic field can be determined by this rule. the thumb, forefinger and middle finger of the left hand mutually at right angles to each other, such that the forefinger is in direction of flux, and the middle finger is in a direction of current flow in the conductor, then the thumb indicates the direction of motion of the conductor.
Can you tell me The working of DC motor?
A DC motor works on the principle of Faraday's law of electromagnetic induction, i.e., when a current carrying conductor is placed in a magnetic field, it experiences a force applied on it.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".
