Answer is B.
Does a charged particle moving through a magnetic field always experience a force? Explain.
Yes, a charged particle moving through a magnetic field always experiences a force. This force, known as the Lorentz force, is perpendicular to the particle's velocity and the magnetic field direction. It causes the particle to move in a curved path. The magnitude of the force depends on the charge, velocity, and strength of the magnetic field.
