Which one is suitable for circular trajectory of a charged particle:
Correct answer: A. Magnetic field
- A. Magnetic field
- B. Electric field
- C. Conservative field
- D. Gravitational field
Explanation
A charged particle moving in a magnetic field experiences a force perpendicular to both its velocity vector and the magnetic field direction, as described by the Lorentz force law. This force causes the charged particle to move in a circular path if its initial velocity is perpendicular to the magnetic field lines. This phenomenon is known as magnetic deflection.The magnetic field is crucial for circular trajectories in devices like cyclotrons, where charged particles are accelerated in a circular path by alternating electric fields and magnetic fields.

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.
