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 causes electrons to move through a wire as a current?
A voltage, which is related to a change in an electric field.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What is the difference between field current and voltage?
Field Current in a DC Motor is the flow of electrons through the field circuit by a field controller. The flux of the motor, that with the armature current generates torque, is directly proportional to the field current. Field Voltage is the electrical potential energy applied on the field circuit by a field controller. Legacy Field Controllers controlled the field voltage. Using I=V/Z (Z=R+iX) the field current is then indirectly controlled. Due to the heat generated by E=i2 R t in the motor, the resistance R would decrease, increasing the field current and therefore changing the base speed of the motor and disturbing the control. Newer field controllers control the field current eliminating this problem
How is the induced voltage of separately excited dc generator affected if the exciting current is reduced?
In a separately excited DC generator, the induced voltage is directly related to the magnetic field strength produced by the field winding, which is influenced by the exciting current. If the exciting current is reduced, the magnetic field strength decreases, leading to a reduction in the induced voltage. Consequently, the output voltage of the generator will decrease as the field strength diminishes, assuming all other factors remain constant.
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.
What is paramedical?
any of the technical course or the certified course which is related to the medical field is called paramedical
What is the relationship between the electric field and current in a circuit?
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
Magnetism and an electric current are related because?
they both produce a magnetic field :)
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 description changes its course once a current is set in motion?
A compass needle changes its course once a current is set in motion. The magnetic field around the current causes the needle to align in a new direction.
Does amperage matter in induction motors?
Of course current matters! If you didn't have a current, then you wouldn't have a magnetic field; without a magnetic field, you wouldn't get any torque, and the motor wouldn't work!
What is field current?
What is field current
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.
In current world what is best field?
Current world best field is IT Field.
What causes electrons to move through a wire as a current?
A voltage, which is related to a change in an electric field.
When a wire carries an electric current it products a?
It produces a magnetic field. Vice versa, when you run a magnet past a wire you generate an electric current. Electricity and magnetism are related. If you have electricity you can generate magnetism, if you have a magnet you can produce electricity.
