Question
Two parallel wires each carry a current I in the positive x direction.
Part A
What is the direction of the magnetic field at any point that lies midway between the wires and in the plane defined by them?
What is the direction of the magnetic field at any point that lies midway between the wires and in the plane defined by them?
The magnetic field is in the negative x direction.
THERE IS ONLY ONE ANSWER AND A VISUAL WOULD BE HELPFUL
The magnitude of the resultant magnetic field is zero. The magnetic field is in the negative y direction. The magnetic field is in the positive z direction. The magnetic field is in the positive x direction. The magnetic field is in the negative z direction. The magnetic field is in the positive y direction.The magnetic field is in the negative x direction.
Explanation / Answer
Ans A
The magnitude of the resultant magnatic field is zero.
The direction of the magnetic field due to moving charges will also depend on the right hand rule. So because of one wire field lines are comming out of plane and because of other field lines are going inside the plane. So net resultant will be zero.
