It is related to the flow of electrons in a conductor through aseparate magnetic field. If you point your index finger straight place your thumb up and place your middle finger at a 90 degree angle to the other two (unless you are really double jointed there is only one way to do it.). The direction of current and your wire is the middle finger the direction of magnetic plane pointing north is your index finger and the direction of force is your thumb.
There is also the right hand rule. If you look at your right hand with your thumb up and fingers curved, If you held a piece of wire in your hand with the current traveling along the direction of your thumb the magnetic field would rotate in the direction of your fingers.
What else can I help you with?
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
What is produced around a wire that has a current?
Magnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
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.
How is the movement of electrons in a conductor related to the formation of magnetic field?
When electrons move through a conductor, they create a flow of electrical current. This flow of current generates a magnetic field around the conductor in accordance with Ampere's law. The strength of the magnetic field is directly related to the magnitude of the current and the distance from the conductor.
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
How can turning off the electric current in an industrial electromagnet affect its magnetic field?
Turning off the electric current in an industrial electromagnet will cause the magnetic field to weaken or disappear as there is no longer a flow of electricity to generate the magnetic field. The strength of the magnetic field is directly related to the amount of current flowing through the electromagnet.
Magnetism and an electric current are related because?
they both produce a magnetic field :)
Does a wire with no current have a magnetic field?
Yes, a wire with no current flowing through it does not produce a magnetic field. Current flow is required to generate a magnetic field around a wire.
Why can an electric current create a magnetic field?
An electric current creates a magnetic field because moving charges generate a magnetic field around them according to the right-hand rule. This magnetic field is perpendicular to both the direction of the current and the surrounding space. The strength of the magnetic field is dependent on the magnitude of the current.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
How is the torque on a loop of current in a magnetic field determined when considering the interactions between the magnetic field and the current loop?
The torque on a loop of current in a magnetic field is determined by the interactions between the magnetic field and the current loop. This torque is calculated using the formula x B, where is the torque, is the magnetic moment of the loop, and B is the magnetic field strength. The direction of the torque is perpendicular to both the magnetic moment and the magnetic field.
When is the force on a current carrying wire in a magnetic field at its strongest?
