Path Covered by Charge Particle Moving in Magnetic field
Case 1: When Particle moving parallel to magnetic field or in the direction of magnetic field.
If particle is moving in the direction of magnetic field then the angle between speed of particle and magnetic field will be zero. It means θ = 0°
From the equation F = qvBsinθ
F = 0
So path will be in straight line.
Case 2: When Particle moving antiparallel to magnetic field or in the opposite direction of magnetic field.
If particle is moving in the opposite direction of magnetic field then the angle between speed of particle and magnetic field will be 180°. It means θ = 180°.
From the equation F = qvBsinθ
F = 0 (sin180 = 0)
So path will be straight line.
Case 3: Case 2: When Particle moving perpendicular to magnetic field.
If particle is moving in the perpendicular to magnetic field then the angle between speed of particle and magnetic field will be 90°. It means θ = 90°.
From the equation F = qvBsin90
F = qvB (sin90 = 1)
So path will in circular.
