Radius in magnetic field
r = mv/(qB)
Where: B = magnetic field (T), m = mass (kg), q = charge (C), r = radius / distance (m), v = final velocity / speed (m/s)
Solved example
Given: B = 7, m = 5, q = 10, v = 4
Find: r (radius / distance (m))
- Formula: r = m·v/(B·q)
- Substitute the values: r = 4·5/(10·7)
- Result: r = 0.285714 m
Answer: r = 0.285714 m
Calculator
