Which of the following statements is INCORRECT?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A charge moving parallel or antiparallel to the direction of the magnetic field experiences a magnetic Lorentz force.
A moving charge produces a magnetic field which can exert a force on another moving charge – True
An electric charge always experiences a force in an electric field, whether stationary or moving – True
A charge moving parallel or antiparallel to the magnetic field experiences a magnetic Lorentz force – False; magnetic force is $F = q \mathbf{v} \times \mathbf{B}$ and is zero if velocity is parallel or antiparallel to $\mathbf{B}$
A stationary charge does not produce a magnetic field to interact with an external magnetic field – True
Incorrect statement: A charge moving parallel or antiparallel to the direction of the magnetic field experiences a magnetic Lorentz force
