The figure shows a uniform magnetic field "B" directed to the left and a wire carrying a current into the page. The magnetic force acting on the wire is:
Correct answer: A. Toward the top of the page
- A. Toward the top of the page
- B. Toward the left
- C. Toward the bottom of the page
- D. Toward the right
Explanation
F=(LxB) F direction= positive y- direction (toward the top of the page)Answer and Explanation:Next, curl your fingers in the direction of the magnetic field (to the left). Your thumb will point in the direction of the magnetic force: upward toward the top of the page. Thus, the magnetic force acting on the wire is a) toward the top of the page. The other options are not correct.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
