A solenoid that is 35 cm long and contains 450 circular coils 2.0 cm in diameter carries a 1.75-A current.
(a) What is the magnetic field at the center of the solenoid, 1.0 cm from the coils?
(b) Suppose we now stretch out the coils to make a very long wire carrying the same current as before. What is the magnetic field 1.0 cm from the wire's center? Is it the same as that in part (a)9 Why or why not?
