In current world what is best field?
Current world best field is IT Field.
In synchronous motor theory is excitation current the same as field current?
Yes, in synchronous motor theory, excitation current is the same as field current. This current is used to produce the magnetic field in the rotor that interacts with the stator current to generate torque and make the motor operate synchronously.
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.
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 statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
How do electric generators produce a current?
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
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
When is the force on a current carrying wire in a magnetic field at its strongest?

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.
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 is the relationship between the surface current density and the magnetic field on a current sheet?
The surface current density on a current sheet is directly proportional to the magnetic field it produces. This means that as the surface current density increases, the strength of the magnetic field also increases.
