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.
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 form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
Can electricity cause a magnetic effect?
Yes, a current carrying conductor behaves like a magnet.
Force on a current-carrying conductor?
Torque
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.
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
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
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.
How will you describe the magnetic field around a straight current carrying wire?
Yes, if you place your thumb in the flow direction, the magnetic direction around the wire will be ccw.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
Why cannot the B-field of an infinitely long straight current-carrying conductor have a component in the direction of the current?
As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer
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
