The magnetic field around a straight current carrying conductor or wire can be increased by bending the wire into circular loop.
A circular loop is made up of large number of very small straight wires.A magnetic field is produced by an electric current flowing through a circular coil of wire.Each small section of current carrying wire contributes to magnetic field lines.
At the centre of circular wire,field lines become straight and perpendicular to the plane of coil.Right hand thumb rule is used to determine the direction of magnetic field produced due to current carrying circular wire.

Magnetic Field around a Straight Wire with Current
When an electric current passes through a straight wire, it generates a magnetic field around the wire. This phenomenon is known as the right-hand rule, which states that if you point your thumb in the direction of the current flow, your curled fingers will indicate the direction of the magnetic field.
Direction of the Magnetic Field
The magnetic field around a straight wire is circular in shape. The direction of the magnetic field lines is perpendicular to the plane formed by the wire and the direction of the current.
Right-Hand Rule for Magnetic Field
The right-hand rule can help determine the direction of the magnetic field around a straight wire. The rule states that if you grip the wire with your right hand, with your thumb pointing in the direction of the current, the curled fingers will indicate the direction of the magnetic field.
Visualizing the Magnetic Field
To visualize the magnetic field around a straight wire, imagine looking at the wire from a bird's-eye view. The magnetic field lines will appear as concentric circles around the wire. The circles closest to the wire indicate a stronger magnetic field, while the circles further away represent a weaker field.
Properties of the Magnetic Field
The magnetic field around a straight wire has the following properties:
- The magnetic field lines are always closed loops and do not have a start or end point.
- The magnetic field strength decreases as you move further away from the wire.
- The magnetic field lines never intersect each other.
- The magnetic field is strongest near the wire and becomes weaker as you move away from it.
Conclusion
When an electric current passes through a straight wire, the associated magnetic field is circular in shape. The direction of the magnetic field lines is perpendicular to the plane formed by the wire and the direction of the current. This phenomenon can be visualized using the right-hand rule, where the direction of the magnetic field is determined by the direction of the current flow.
