A flat, 179 179 ‑turn, current‑carrying loop is immersed in a uniform magnetic field. The area of the loop is 4.41 cm 2 4.41 cm2 and the angle between its magnetic dipole moment and the field is 59.9 ∘ . 59.9∘. Find the strength B B of the magnetic field that causes a torque of 2.25 × 10 − 5 N ⋅ m 2.25×10−5 N⋅m to act on the loop when a current of 2.49 mA 2.49 mA flows in it.

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
