A solenoid (coil) of radius R has 10 turns per centimeter. It is 10cm long, and the coiled wire carries a current I. In addition to the coil of wire, a second wire runs right down the central axis of the solenoid, carrying a current of 2I. (The solenoid wire doesn't intersect this second wire, because the former wraps around the latter, always a distance R away.) A) Find the magnitude of the total magnetic field at a distance R/2 from the central wire.
Will there be a magnetic force between the two wires? Why or why not?

A coil of 15 turns and radius 10.0 cm surrounds a long solenoid
of radius 2.10 cm and 1.00 103 turns/meter

I = 4.00 sin 120 t, where I is in
amperes and t is in seconds. Find the induced emf (in
volts) in the 15-turn coil as a function of time.

An ideal solenoid, of radius R and n turns per unit length, has
a current flowing through it. The current, I, varies with time, t,
according to I = I0 + at where I0 and a are constants. A conducting
ring of radius, r, is placed inside the solenoid with its axis
coinciding with the axis of the solenoid. The ring has a resistance
per unit length of H (in units of Ω/m).
