dc flux is caused by dc current (flux and current are proportional), it is a constant value. Put an inductor (or transformer winding) across a battery and you will get dc flux.
ac flux is caused by ac current (flux and current are proportional), it is a moving value, the flux moves with the current, typically cyclical but the waveform is arbitrary as long as we're moving.

What is the differences between the slip and split rings?
Split rings are in AC generators ( alternating current) while slip rings are in DC current (direct current).
AC operation of magnetic circuit?
DC sources are not used for excitation of magnetic circuit of transformers and other AC machines. AC sources are used. The steady-state current is calculated by the applied voltage and resistance of the circuit when DC excitation is applied. The inductance in this case plays the role only for the transient part. The adjustment of the magnetic flux takes place as per the value of current to satisfy the relationship of B-H curve or magnetization curve. For the case of AC excitation, inductance comes into picture for steady-state performance. The flux is determined by the impressed voltage and frequency. The adjustment of magnetization current takes place as per the value of this flux to maintain the relationship imposed by the magnetization ....
Magnetic flux density is measured by q meter or ac voltmeter or hall probe or energy meter?
Hall Probe. When the Hall Probe is held so that the magnetic field lines are passing at right angles through the sensor of the probe, the meter gives a reading of the value of magnetic flux density (B).
Is DC is at low voltage than ac?
There's no correlation between the voltage, the current, and whether the source is AC or DC.
What is difference between an AC and DC flux?
As happens with voltage and current, flux is steady for dc but keeps altering for ac. A transformer works through the ac flux in the magnetic core.
Is flux only produce in ac supply or in both ac and dc?
Flux is produced in both AC and DC systems, but the nature of the flux differs. In DC circuits, the magnetic flux is constant, as the current flows in one direction. In AC circuits, the magnetic flux changes direction and magnitude periodically, resulting in a time-varying magnetic field. Thus, while both types of current can produce flux, AC generates a dynamic flux due to its oscillating nature.
Flux in DC vary or constant.?
In DC or direct current, the flux is constant. AC or alternating current is variable.
Why transformer do not operate with DC?
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
What What is the difference between buzzer and speaker?
BUZZER IS SIMPLY A RELAY THAT MECHANICALLY OPENS AND CLOSES. A speaker is a coil suspended into a magnetic flux responding to AC signals
What is ac flux in transformer?
The flux means the flux of the magnetic field passing through the iron core of the transformer. Because the applied voltage is AC, it means that the flux is also AC. The voltage and the flux are related by the basic formula v = N d/dt (phi) where N is the number of turns in the coil. At a steady frequency this becomes: v = N x 2pi x freq x (total flux in Webers) This is the basic design equation for transformers because the peak flux density in the core sets a physical limit and determines the size of the transformer, which is why transformers are always larger at lower frequencies.
What is the difference in welding rods for ac welders and dc welders?
The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.
What are the main differences between a window AC and a wall AC unit, and which one would be more suitable for my specific needs?
The main differences between a window AC and a wall AC unit are their installation methods and size. A window AC unit is designed to fit in a window opening, while a wall AC unit is mounted through a wall. For your specific needs, consider the space available for installation. If you have a suitable window and want a more portable option, a window AC unit may be more suitable. However, if you prefer a more permanent and integrated solution, a wall AC unit could be a better choice.
What are the key differences between AC and DC current, and how do these differences impact the efficiency of electrical systems?
AC (alternating current) and DC (direct current) differ in the direction of flow and voltage fluctuation. AC changes direction periodically, while DC flows in one direction. AC is more efficient for long-distance transmission due to lower energy loss, but DC is better for certain devices like electronics. The choice between AC and DC depends on the specific application and efficiency requirements of the electrical system.
What are the key differences between DC and AC current, and how do these differences impact their applications in various electrical systems?
Direct current (DC) flows in one direction continuously, while alternating current (AC) changes direction periodically. DC is commonly used in batteries and electronic devices, while AC is used in power grids and household appliances. The differences in current types impact their efficiency, transmission, and safety in different electrical systems.
