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.

Why are all cores exposed to ac flux variation laminated?
Limit effects (heat loss) caused by eddy currents
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).
What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
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.
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?
AC flux in a transformer refers to the alternating magnetic field that is generated when an alternating current flows through the primary winding. This changing magnetic field induces a voltage in the secondary winding, allowing for the transfer of electrical energy from one coil to another. The AC flux is essential for the transformer to function and facilitate the conversion of voltage levels.
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.
Where can I find a converter for AC adaptors online?
Dvd Overseas has a great variety of AC adapter converters available to buy online. It also provides a comprehensive list of information on the differences between each converter.
Why are all cores exposed to ac flux variation laminated?
Limit effects (heat loss) caused by eddy currents
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).
What are the main differences between AC and DC currents?
An AC waveform is a sine wave and varies from positive to negative with a frequency of 60 Hertz (Cycles per Second). DC is a constant voltage and does not vary like the sine wave.
What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.
