Only part b.
Transcribed Image Text:1. A good approximation of the size of a turkey is by assuming it to be
spherical. Suppose that we plan to cook it rotisserie style in a uniform
magnetic field, on a singular rotating circular and conductive wire with radius
r and current i, respectively. The turkey has a uniform density as Pt and
mass m.
(a) We've came up with an idea on how motors work. Express and explain
the equation for torque in a current carrying loop in a uniform magnetic
field. Do not derive the problem.
