The diagram below shows a straight wire carrying a conventional current into the page. The wire is between the poles of a permanent magnet. The direction of the magnetic force exerted on the wire is: A. upward. B. to the left. C. downward D. into the page. E. to the right.
Answer key says C. downward; please explain. Thanks!
Homework Answers
intgis problem we need to consider the Fleming's left hand rule
stretch your right hand thumb ( will give direction of force) , index finger ( direction of magnetic field) and middle finger( directionof current ) in such a way that each of them are mutually perpendicular to each other. now allign your index finger to the right (magnetic field), middle finger into the page (current), then thumb will alligned in downward direction.
so option (c) is correct

Comment in case any doubt, will reply for sure. Goodluck
