Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you. The lines of magnetic force at any point in the magnetic field will act in?
A clockwise direction
How can the magnetic field produced around a current carrying conductor be detected?
One simple method is to use a compass.
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 are examples of electromagnetic force?
The simplest and effective example is the current carrying conductor placed in a magnetic field.whose applications are motor,generator etc
How was the first man made magnet made?
Hans Oersted, a Dane, was the first to observe the magnetic effect of a current carrying conductor - about 1819.
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.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
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
What is magnetoresistence?
The change in electrical resistance produced in a current carrying conductor or semiconductor on application of magnetic field H.
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.
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
If a conductor carrying an alternating current is formed into a coil the magnetic field that is generated?
If the current is alternating, the magnetic field will also be alternating.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
What is the shape of magnetic lines force in case of a straight current carrying conductor?
circular
Inductive ammeters work because of what principle?
Inductive Ammeters do not make physical contact with the circuit, but measure the strength of the magnetic field surrounding the wire carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.This means that the meter probe surrounds the wire(s) carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and 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
