What to enter
| Input | Meaning and units |
|---|---|
| Charge magnitude (C) | Enter charge magnitude in C; use the same basis as the other measurements. |
| Speed (m/s) | Enter speed in m/s; use the same basis as the other measurements. |
| Field strength (T) | Enter field strength in T; use the same basis as the other measurements. |
| Velocity-to-field angle (degree) | Enter velocity-to-field angle in degree; use the same basis as the other measurements. |
Understanding your result
Read Magnetic force magnitude (N) in the units and model stated on this page. The formula force=q*v*B*sin(angle*pi/180) defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
