Torque:

The torque (also moment) about an axis, due to a force, is a measure of the effectiveness of the force in producing
rotation about that axis. The torque equation is:

**τ = rFsinθ**

Where:

θ: The acute angle between the radial and force lines

r: The radial distance from the axis to the point of application of the force

F: The force

The torque on a looped coil, each carrying a current, in an external magnetic field is:

**τ = NIABsinθ**

Where:

θ: The angle between the field lnes and a perpendicular to the plane of the coil

I: Current

A: Area of the coil

B: Magnetic field

N: Coil loops number
