The charged particle enters the uniform magnetic field in such a way that its initial velocity is not perpendicular to the field, the orbit will be
Correct answer: B. A spiral
- A. A circle
- B. A spiral
- C. An ellipse
- D. A helix
Explanation
When a charged particle enters a uniform magnetic field with an initial velocity that is not perpendicular to the field, the orbit it follows can be determined by considering the Lorentz force acting on the particle. When the initial velocity isn't perpendicular to the magnetic field, the resulting path can be a spiral. The particle's trajectory curves due to the combined effect of the magnetic force and its initial non-perpendicular velocity.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
