How does the current in the primary winding create an alternating magnetic field in the core?

Relationship between Current and Magnetic Field:

When a current passes through a conductor, a magnetic field will be generated around the conductor. For a transformer, the current in the primary winding will generate a magnetic field in the iron core. The specific steps are as follows:

The current passes through the primary winding：

• AC power supply: Ang primary windings sa transformer giconnect sa AC power source, ug ang current gihatag sa AC power source is alternating, i.e., ang direction ug magnitude sa current periodically change with time.

• Current waveform: Assuming that the current waveform of the AC power supply is a sine wave, it can be expressed mathematically as I(t)=I0sin(ωt)  ，whereI0  is the maximum value of the current,ω is the angular frequency,t is time.

 Generation of magnetic field：

• Generation of magnetic field: When the alternating current passes through the primary winding, a magnetic field will be generated around the winding. According to Ampère's circuital law, the magnetic field strength 
  B  generated by the current in a closed loop is proportional to the current.

• Direction of magnetic field: Ang direction sa magnetic field mahimong mapahayag pinaagi sa right - hand rule. Point the thumb of the right hand in the direction of the current, and the direction in which the four fingers curl is the direction of the magnetic field.
