The orientation of small satellites is often controlled using toque from current- carrying coils in Earth's magnetic field. Suppose a multiturn coil has a cross-sectional area of 6.36 10-4 m2, dissipates 0.200 W of electrical power from a 5.00 V power supply, and provides a magnetic moment of magnitude 0.0200 Am2. (a) Find the coil current I. (b) Calculate the maximum magnitude of torque if Earth's magnetic field has magnitude 3.75 10-5 T at the satellite's location.
