Always towards the wire
Always away from the wire
Depends on the direction of current
Always perpendicular to the wire
The direction of the magnetic field produced by a current-carrying wire depends on the direction of the current, as determined by the right-hand rule.

Q: What is the direction of the magnetic field produced by a current-carrying wire when viewed from one end? (2023)
Solution: The direction of the magnetic field produced by a current-carrying wire depends on the direction of the current, as determined by the right-hand rule.
Steps: 4
Step 1: Identify the direction of the electric current flowing through the wire. This can be from positive to negative.
Step 2: Use your right hand to apply the right-hand rule. Point your thumb in the direction of the current.
Step 3: Curl your fingers around the wire. The direction your fingers curl represents the direction of the magnetic field lines.
Step 4: If you are looking at one end of the wire, the direction of the magnetic field will be in the direction your fingers point.
