A current-carrying wire acts as a __
with a __ Around it

Answer 1

A current-carrying wire acts as a Magnet with a Magnetic Field around it.

• A current-carrying conductor behaves like a magnetic field.
• The magnetic field lines around a current-carrying wire are concentric circles with wire at its center.
• The direction of the magnetic field can be found out using Right Hand Thumb Rule.
• According to this, hold your right hand such that the thumb points in the direction of the current. The curled fingers show the direction of field lines.
