The path of a moving charged particle in a magnetic field is ……… * 1 point linear circular spiral downward

The path of a moving charged particle in a magnetic field is circular.

Here's why:

1. When a charged particle enters a magnetic field perpendicularly, it experiences a magnetic force. This force is always perpendicular to the velocity of the particle.

2. According to Fleming's left-hand rule, the force acts towards the center of a circle. This force provides the necessary centripetal force for circular motion.

3. Therefore, the path of a moving charged particle in a magnetic field is circular.

However, if the particle enters the field at an angle other than 90 degrees, the path will be a spiral. This is because the component of velocity parallel to the field is unaffected, causing the particle to move along the field lines as it circles.
