B. a current carrying loop of wire tends to line up with itsplane parallel to an external magnetic field in which it ispositioned. C. The magnetic force on a moving charge does not change itsenergy. D. Magnetic force on a moving charge does not change itsenergy. E. the magnetic force on a current carrying wire is greatestwhen the wire is parallel to the magnetic field A. a magnetic field line is, by defination, tagent to thedirection of the magnetic force on a moving charge at a given pointin space.

D. Magnetic force on a moving charge does not change itsenergy. E. the magnetic force on a current carrying wire is greatestwhen the wire is parallel to the magnetic field
Explanation / Answer
In the above given statements , the accurate statement is: (A) A magnetic field line is, bydefination, tagent to the direction of the magnetic force on amoving charge at a given point in space . These lines are calledMagnetic lines of force. Hope this helps u!
