Question

a square horseshoe magnet contains magnetic wire wound around a center core.
true
false

Explanation:

Analyze the construction of a square horseshoe electromagnet

Using the Electromagnetism knowledge point
An electromagnet is constructed by winding a conductive wire (often called magnet wire) around a ferromagnetic core. A horseshoe magnet (including a square-shaped horseshoe magnet) has a U-shape with two parallel legs connected by a yoke. To create an electromagnet using this core, the wire is wound around the legs (or poles) of the horseshoe core, rather than a single "center core," because a horseshoe shape does not have a central core column like a shell-type transformer or a three-legged core. Winding the wire around the legs concentrates the magnetic flux at the two adjacent pole faces, creating a strong magnetic circuit. Therefore, stating that a square horseshoe magnet contains wire wound around a "center core" is structurally incorrect.

Answer:

• True
• (B) False (Correct answer)
