Formulas and Key Relations

2. Magnetic field lines and dipole behavior

τ = m × B

τ = mB sinθ

U_m = -mB cosθ = -m·B

3. Bar magnet as equivalent solenoid

B = (μ0/4π)(2m/r^3)

B_E = -μ0 m /(4π r^3)

B_A = (μ0/4π)(2m/r^3)

Key relations

The potential energy of a magnetic dipole in a uniform field is U_m = -m · B = -mB cosθ.

It is minimum at θ = 0° and maximum at θ = 180°.
