1. A long straight wire has a current of 6 A. Calculate the magnetic field produced by the current from a 2-cm wire at a point 0.25 m directly above the given portion of the wire.


2. A wire is shaped into a coil of 180 turns, each with a radius of 1.5 cm. If the current in the wire is 12 mA, find the magnitude of the magnetic field at the center of the coil.
