A charged particle moves in a magnetic field. What is the condition for the particle to experience no magnetic force?

Step 1: Understand that a charged particle can experience a magnetic force when it moves in a magnetic field.
Step 2: Know the formula for magnetic force: F = q(v × B), where F is the force, q is the charge, v is the velocity of the particle, and B is the magnetic field.
Step 3: Recognize that the '×' symbol represents the cross product, which means we are looking for a specific relationship between the velocity vector (v) and the magnetic field vector (B).
Step 4: Realize that the cross product is zero when the two vectors (v and B) are parallel to each other.
Step 5: Conclude that for the charged particle to experience no magnetic force, its velocity (v) must be parallel to the magnetic field (B).

Magnetic Force on Charged Particles – The magnetic force on a charged particle is determined by the equation F = q(v × B), where F is the force, q is the charge, v is the velocity, and B is the magnetic field. The force is zero when the velocity is parallel to the magnetic field.
Cross Product – The cross product of two vectors is zero when the vectors are parallel or anti-parallel, which is crucial for understanding when a charged particle does not experience a magnetic force.
