The direction of the magnetic field lines produced when a current is passed through a conducting wire, from the conductor isA perpendicular, outside B perpendicular, inside C parallel D circular around it

The direction of the magnetic field lines produced when a current is passed through a conducting wire from the conductor is circular around it. So, the correct answer is D. Circular around it.

Here's a step-by-step explanation:

1. When a current is passed through a conducting wire, it creates a magnetic field around it. This is known as Ampere's Circuital Law.

2. The direction of this magnetic field is always perpendicular to the direction of the current.

3. If you use your right hand and point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field. This is known as the right-hand rule.

4. Therefore, the magnetic field lines form concentric circles around the wire, making the direction of the magnetic field lines circular around the wire.
