Answer:

A. up

B. counter clockwise

Step-by-step explanation:

Note: it looks to me like the picture was taken looking down on a the hand resting on a tabletop, with the thumb pointing UP. If this is correct then the answer is:

According to the Curl Right Hand Rule for magnetic fields, the fingers curl in the direction of the magnetic field and the thumb points in the direction of the current, therefore:

current is flowing UP

magnetic field direction is counter clockwise

Direction is the current flowing is Up.

The magnetic field direction would be clockwise

Using the right-hand rule, if the current flows out of the screen, your fingers curl counterclockwise, indicating the magnetic field is also counterclockwise.

Conversely, if the current is flowing into the screen, your fingers would curl clockwise, denoting a clockwise magnetic field direction.

The question presents a scenario using the right-hand rule to determine the direction of current and the magnetic field around a wire.

When you point your right-hand thumb in the direction of the current, your fingers will curl in the direction of the magnetic field.

If the thumb is pointing upward, indicating that the current is flowing upwards, your fingers would curl counterclockwise, which implies that the magnetic field goes counterclockwise around the wire.

Conversely, if the thumb points down, then the magnetic field curls clockwise. In the scenario with a thumb pointing out of the screen (current flowing out), the fingers would curl counterclockwise, indicating that the magnetic field around the wire is in that direction.

If the thumb were pointing into the screen (current flowing in), your fingers would curl clockwise; thus, the magnetic field direction would be clockwise.
