Force Magnétique sur Charge

How to use it

1. Charge q = 1.5×10⁻⁶ C, velocity v = m/s
2. Magnetic field B = 0.8 T, angle θ = 60°
3. Calculate sans(60°) ≈ 0.8660
4. Force: 1.5×10⁻⁶ × 2500 × 0.8 × 0.≈ 0.0026 N

Common mistakes

• ⚠️ Using degrees directly without radian conversion in sine
• ⚠️ Forgetting that force is zero when θ = 0° or 180°
• ⚠️ Confusing magnetic force with electric force (no sans term)

Worked example

Find magnetic force on a 1.5 μC charge moving at m/s through 0.8 T field at 60°.

The magnetic force {force} N acts perpendicular to both velocity and magnetic field.
