Why is it misleading to call magnetic field lines lines of force?
AThey are not continuous curves
BThey carry no energy at all
CThey never show field strength
DForce on a charge is normal to B
Answer & Solution
Correct answer: D. Force on a charge is normal to B
Since force is q v cross B, it is perpendicular to the field, not along the field line.
