vertical wire carries an electric current out of the page. What is the direction of the magnetic field at point P located to the west from the wire?
Answers
The direction of the magnetic field at point P located to the west from the wire will be at South.
It can be determined by Right Hand Thumb Rule.
The Right Hand Thumb rules state that if thumb of the right hand points along direction of current, then the remaining curled , fingers of same hand gives the direction of the magnetic field due to the current.
One can also get the direction of magnetic flied using Flemming's Left Hand rule.
Fleming’s Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left hand perpendicular to each other, then the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of the magnetic field and the middle finger points towards the direction of the current.

Answer:
The direction of the magnetic field at the point P, west of the wire, will be towards the South.
Explanation:
As we know, the direction of the magnetic field with respect to the electric field can be found out from Fleming's Right Hand Thumb Rule.
The rule state that if the right thumb points along the direction of the current, then the remaining fingers, when curled, give the direction of the magnetic field due to the current.
We can also find this out using Fleming's Left Hand Rule. It states that when we arrange our left thumb, forefinger, and middle finger mutually perpendicular, the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of the magnetic field, and the middle finger points towards the direction of the current.
