Q. The net charge in a current carrying wire is zero still magnetic field exerts a force on it, because a magnetic field exerts force on
Moving Charges and Magnetism
A
Stationary charge
33%
B
Moving charge
49%
C
A positive charge only
11%
D
A negative charge only
7%
Solution:
$F=q(\vec{V} \times \vec{B})$
Moving charge are only electrons and magnetic field exert force on moving charges only.
