Question

A straight wire of 0.3 m carrying a current of 2 A in the downward direction is placed in a magnetic field of 0.1 T as shown in the figure. Find out the direction of the force on the wire?

• A. Into the page
• B. Out of the page
• C. Toward the top of the page
• D. Toward the bottom of the page
• E. To the left

Answer 1

The correct option is B Out of the page

The direction of magnetic force on a current carrying conductor placed perpendicular to the magnetic field is given by Fleming's left hand rule. Using this rule, it can be concluded that the direction of force on wire is out of the page.
