Detailed Solution

Faraday's law describes how changing magnetic fields can cause current to flow in wires.
Columb's law explains the force between the charges.
Newton's law describes the motion of objects.
The direction of the magnetic field due to a current-carrying conductor can be decided using the Right-hand thumb rule.
It states that if you point your thumb in the direction of the current, then the direction of the curl of your fingers gives the direction of the magnetic field.

Therefore, Right-hand thumb rule' is the correct response.
