The work done by a magnetic field, on a moving charge is

• A. zero because $\vec{F}$ acts parallel to $\overrightarrow{v}$
• B. positive because $\vec{F}$ acts perpendicular to $\overrightarrow{v}$
• C. zero because $\vec{F}$ acts perpendicular to $\overrightarrow{v}$
• D. negative because $\vec{F}$ acts parallel to $\overrightarrow{v}$

Answer 1

Answer: (C)

Correct answer is (c) zero because $\vec{F}$ acts perpendicular to $\overrightarrow{v}$
