Given Information:
Magnetic field = B = 0.480 T
Current = I = 23.3 mA = 0.0233 A
Number of turns = N = 48 turns
Radius = r = 5.50 cm = 0.055 m
Required Information:
Maximum possible torque = τ = ?
Answer:
Maximum possible torque = 0.0051 N.m
Explanation:
We know that toque τ is given by
τ = NIABsin(θ)
Where N is the number of turns of the circular coil, I is the current flowing through the circular coil, A is the area of circular coil, B is the magnetic field induced in the circular coil.
The area of the circular coil is
A = πr²
A = π(0.055)²
A = 0.009503 m²
The maximum torque is possible when θ = 90°
τ = 48*0.0233*0.009503*0.480*sin(90°)
τ = 0.0051 N.m
