а. A sоlenоid 10.0 cm in diаmeter аnd 75.0 cm lоng is made from copper wire of diameter 0.100 cm, with very thin insulation. The wire is wound onto a cardboard tube in a single layer, with adjacent turns touching each other. What is the current to the solenoid if it is to produce a field of 8.00 mT at its center? (5 pts) b. A transformer has 700 primary turns and 9.6 secondary turns. (a) If Vp is 120 V (rms), what is Vs with an open circuit? If the secondary now has a resistive load of 19 Ω, what is the current in the (b) primary and (c) secondary? (5 pts)
