Earth When you bring a currentcarrying wire down onto the to

Earth When you bring a current-carrying wire down onto the top of a compass, aligned with the original direction of the needle the needle deflects by e E 14 degrees (as shown above). Which of the following statements are correct? A. The magnetic field under the wire, due to the current, points north B. The magnetic field under the wire, due to the current, points to the East. C. The magnetic field under the wire, due to the current, points to the West D. Conventional current in the wire flows upward (North) E. Electron current in the wire is flowing upward (North) F Conventional current in the wire is flowing downward (South) A and D C, E, and F B and D B, E, and F

Solution

Here ,

theta = 14 degree

as the needle deflects in the direction of magnetic field due to wire at the location.

direction of magnetic field due to earth is towards north

hence , the magnetic field due to wire is towards east

hebce , the correct options are

B , E , F

the correct option is last

B, E and F
