1. A long solenoid of length 8 m with a cross-sectional area of 5.0 x 10-5 m2 contains a total of 52,000turns.
A) Compute the self-inductance of the solenoid, assuming that the core of the solenoid is air.
B) If the current in the winding starts at 0 A and is increased steadily to 1.5 A in a time of 0.20 sec, what is the EMF induced in the solenoid?
2. A permanent bar magnet has a field strength of 1T. Suppose we have a circular wire loop of radius R= 0.50 cm that is carrying a current of I Amperes.
What current is required to create a magnetic field at the center of the wire loop that is equal to the field of the bar magnet?
