The field consists of concentric circles centred on the wire.
On applying right-hand thumb rule, we find the direction of magnetic field. The field is in the form of concentric circles centred on the wire carrying current.
Hence, the option (d) is correct.

The Correct Answer is Option D: The magnetic field near a long straight wire consists of concentric circles centered on the wire.
Explanation:
When an electric current flows through a wire, it produces a magnetic field around it. The magnetic field lines are a representation of the direction and strength of the magnetic field.
Magnetic Field Around a Long Straight Wire:
- The magnetic field near a long straight wire is circular and symmetrical.
- The magnetic field lines form concentric circles around the wire.
- The circles are centered on the wire, with the wire passing through the center of each circle.
- The magnetic field lines are perpendicular to the wire at every point.
- The strength of the magnetic field decreases as you move farther away from the wire.
Visualization:
To visualize the magnetic field around a long straight wire, imagine the wire passing through the center of a piece of paper. The magnetic field lines would be like concentric circles around the wire, as if the wire was the center of a dartboard.
Right-Hand Rule:
To determine the direction of the magnetic field lines, you can use the right-hand rule. Wrap your right hand around the wire with your thumb pointing in the direction of the current flow. Your fingers will then curl in the direction of the magnetic field lines, which are the concentric circles.
Applications:
The magnetic field around a long straight wire has practical applications, such as in electromagnets, solenoids, and electric motors. Understanding the direction and strength of the magnetic field is essential for designing and manipulating these devices.
Summary:
In summary, the correct description of the magnetic field near a long straight wire is that it consists of concentric circles centered on the wire. The magnetic field lines are perpendicular to the wire and decrease in strength as you move farther away from the wire.
