Magnetic Coil Torque Simulation
Demonstration of torque on current-carrying conductors in magnetic fields
Torque Calculation
The torque (τ) on a current-carrying coil in a magnetic field is given by:
τ = n × I × A × B × sinθ
τ = 30 × 6.0 × 0.0201 × 1.0 × sin(60°) = 3.133 Nm
Where:
n = number of turns (30)
I = current (6.0 A)
A = coil area (0.0201 m²)
B = magnetic field strength (1.0 T)
θ = angle between field and normal (60°)
The torque depends only on the enclosed area of the coil, not its shape.
