A2.0-cm-diameter, 15-cm-long solenoid is tightly wound with one layer of wire. a 2.5 a current through the wire generates a 3.0 mt magnetic field inside the solenoid. what is the diameter of the wire, in mm?

d = 1.047 mm

Explanation:

given,

diameter of the wire = 2.0-cm

length of solenoid = 15 cm = 0.15

Current in the wire = I = 2.5 A

magnetic field = B = 3.0 mT

Magnetic field inside the solenoid

               N x d = l

               d = 1.047 x 10⁻³ m

               d = 1.047 mm

diameter of the wire is d = 1.047 mm
