as , the current is moving upward so to determine the magnetic field on the West we will use right hand palm rule.. and it's coming upwards.. ok... see the attachment

Direction of Current in a Straight Wire

The direction of current in a straight wire can be determined using the right-hand rule, specifically the right-hand grip rule. This rule states that if you hold the wire in your right hand with your thumb pointing in the direction of the current, then your fingers will curl in the direction of the magnetic field created by the current.

Right-Hand Grip Rule:
To determine the direction of current in a straight wire, follow these steps:

1. Hold your right hand in a way that your thumb points in the direction of the current.

2. Your fingers will naturally curl around the wire, indicating the direction of the magnetic field.

Direction of Magnetic Field at a Point West of the Wire

To determine the direction of the magnetic field at a point west of the wire, you can apply the right-hand rule again.

Right-Hand Rule:
To find the direction of the magnetic field, follow these steps:

1. Extend your right hand with your thumb pointing in the direction west of the wire.

2. Curl your fingers towards the wire.

3. The direction in which your fingers curl indicates the direction of the magnetic field.

Conclusion

Using the right-hand grip rule, you can determine the direction of current in a straight wire. By applying the right-hand rule again, this time with your thumb pointing west of the wire, you can determine the direction of the magnetic field at that point. Remember to always use your right hand for these rules and visualize the direction of current and magnetic field by curling your fingers.
