Question: The magnetic field lines around a straight current-carrying conductor are: (2022)

Options:

Correct Answer: Concentric circles

Exam Year: 2022

Solution:

The magnetic field lines around a straight current-carrying conductor form concentric circles centered around the wire.

The magnetic field lines around a straight current-carrying conductor are: (2022)

The magnetic field lines around a straight current-carrying conductor are: (2022)

Step 1: Understand that a current-carrying conductor is a wire through which electricity flows.
Step 2: Recognize that when electricity flows through the wire, it creates a magnetic field around it.
Step 3: Visualize the wire as the center point of a circle.
Step 4: Imagine drawing circles around the wire; these circles represent the magnetic field lines.
Step 5: Note that these circles are concentric, meaning they share the same center (the wire) and get larger as you move away from the wire.
