Question

In the American Wire Gauge (AWG) system, a 16-gauge wire has a diameter of 0.0500 inches. A copper wire of this size is only rated to withstand a current of 15 amps. Design an electromagnet that has a magnetic field of 0.18 T at the center.

a) What is the ratio of the number of turns to the radius of the magnet you designed? (Hint: Do this first!)

b) How many turns does your electromagnet have? What is the radius of the electromagnet you designed? (There will be multiple correct answers. Again, go for simplicity.

c) Using your design, how long would the wire have to be?

d) What is the resistance of this length of wire? (Remember you are using a copper wire)

e) What is the voltage you would have to apply to the wire in order to obtain the desired current?
