4. A wire coil used to produce a magnetic field is made of copper wire of diameter 0.7 mm, and is wound so the coil has a diameter of 40 cm (see figure). The resistance of the coil is measured to be 3.7 2. Assume the coil consists of N loops, each with diameter. What is the length of wire used to make the coil? How many loops (N) of wire form the coil? This is an important parameter in determining the magnetic field strength produced by a current-carrying coil. (the wire is not being treated as 'ideal' here) 5. An aluminum wire of diameter 0.10 mm carries a current of 0.25 A. What is the electric field strength inside the wire? (the wire is not being treated as 'ideal' here) 4.
