Question
A circular coil of wire of radius 5.0 cm has 20 turns and carries a current of $2.0 \mathrm{A}$. The coil lies in a magnetic field of magnitude $0.50 \mathrm{T}$ that is directed parallel to the plane of the coil. (a) What is the magnetic dipole moment of the coil? (b) What is the torque on the coil?
Step 1
The magnetic dipole moment (μ) is given by the formula: \[ \mu = nIA \] where n is the number of turns, I is the current, and A is the area of the loop. Show more…
