PLease explain IN DETAIL how to do these TWO problems and those similar to it. THANKS

The next two questions apply to the following: A current-carrying wire is place in a magnetic field as shown in the figure below. 5 A 35 B-0.7T 16. Find the direction of the magnetic force on the wire A. nto the page B, out of the page o c. up and to the right 1 D. Down and to the left E. None the force is zero 17. Find the magnitude of the magnetic force per ength on the wire A. 3.38 N/m B. 3.17 N/m C. 2.87 N/m D. 2.25 N/m E. 0.0 N/m

Explanation / Answer

1. APPLY FLEMING RIGHT HAND RULE

DIRECTION IS OPTION d

2. F = ilB sin theta

F/l = iB sin theta

F/l = 5* 0.7* sin (90-35)

F/l = 2.86 N/m

option C
