Two long, straight wires, one above the other, are separated by a distance 2a and are parallel
Two long, straight wires, one above the other, are separated by a distance 2a and are parallel to the x-axis. Let the +y-axis be in the plane of the wires in the direction from the lower wire to the upper wire. Each wire carries current I in the +x-direction. What are the magnitude and direction of the net magnetic field of the two wires at a point in the plane of the wires? (a) Midway between them; (b) At a distance a above the upper wire; (c) At a distance a below the lower wire?

I teach physics for 3 years, and the best experience that I would like to share is delivering lectures at the college where I studied. I prepare and deliver lectures to undergraduate and graduate students on subfields of physics such as quantum mechanics, solid-state physics, and mechanics. Maintain student attendance and grades.
Irrespective of the basics that an individual has, need to help the student in understanding the core concepts in clarity. In that way, I am able to push my students in understanding the basic logical structure of the subject and excel slowly.
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
