Question

It is desired to construct a solenoid that will have a resistance of 5.60 Ohm (at 20 degree C) and produce a magnetic field of 4.00 ? 10-2 T at its center when it carries a current of 3.40 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20 degree C is 1.7 times 10-8 ? · m.) the number of turns of wire needed to build the solenoid 1040 turns... i already solved this.... the length the solenoid should have?

Explanation / Answer

process can be as with valuea a resistance of 4.80 (at 20
