Formulas and Key Relations

2. Biot-Savart Law

dB = (μ0/4π) · (I dl sinθ)/r²

d𝐁 = (μ0/4π) · I(d𝐥 × 𝐫)/r³

B = μ0I/2πr

B = (μ0/4π)(I/r)(sinφ1 + sinφ2)

B = μ0NI/2a

3. Ampere's Circuital Law and Applications

∮B · dl = μ0I

B = μ0nI0

B = μ0μr n I0

B = (μ0/2π)(NI0/a)

B = (μ0/2π)(I/r)

4. Magnetic Force on a Moving Charge

F = Bqv sinθ

𝐅 = q(𝐯 × 𝐁)

F = q(E + v × B)

r = mv/qB = p/qB

T = 2πm/qB ; n = qB/2πm ; ω = qB/m

Finite straight conductor

B = (mu0/4pi)(I/r)(sin phi1 + sin phi2).

Infinite straight conductor

B = mu0 I / 2pi r.

Key relations

For a straight infinite wire, B = (mu0)/(2 pi) times I/r.
