The direction of the magnetic field produced around a conductor by both DC and AC current flow is the same. This is determined by the right-hand rule:

Right-Hand Rule:

1. Point your thumb in the direction of the current flow.

2. Curl your fingers around the conductor.

3. The direction of your curled fingers represents the direction of the magnetic field lines.

Key Difference:

The magnitude of the magnetic field produced by AC current changes constantly, while the magnetic field produced by DC current is constant. This is because the direction of AC current flow reverses periodically, causing the magnetic field to fluctuate accordingly.

In Summary:

* DC current: Produces a constant magnetic field around the conductor.

* AC current: Produces a fluctuating magnetic field around the conductor, with the field strength changing in accordance with the current's frequency.

Note: While the direction of the magnetic field is the same, the strength of the magnetic field depends on the magnitude of the current. Therefore, a higher current (whether DC or AC) will produce a stronger magnetic field.
