Zorluk: OrtaFundamentals of Electromagnetism and Induction

A straight electrical conductor carries a steady direct current vertically through a flat horizontal surface. Which pattern best describes the magnetic field lines formed around the conductor?

  1. A
    Straight magnetic lines that travel parallel alongside the wire in the direction of current flow
  2. Concentric closed circles centered on the wire in planes perpendicular to the conductorCevap
  3. C
    Radial field lines pointing straight outward from the wire due to expanding voltage pressure
  4. D
    Pulsating magnetic loops that appear only when alternating current flows through the wire

Cevap

Concentric closed circles centered on the wire in planes perpendicular to the conductor
When an electric current passes through a straight conductor, it generates a magnetic field consisting of concentric circular lines of magnetic flux that wrap around the wire in planes perpendicular to the conductor's axis.

Adım Adım Çözüm

1
Identify the relationship between electric current and magnetic fields.
Every electrical current produces a magnetic field surrounding the conductor.
According to the fundamental principles of electromagnetism (Ampère's Law), moving electrical charges inherently generate a magnetic field.
2
Determine the geometry of the magnetic field around a straight wire.
The magnetic flux forms continuous concentric circular loops centered on the wire.
The magnetic field lines lie in planes perpendicular to the direction of current flow, following the right-hand rule.

Anahtar Kavram
