Solenoids are cylindrical coils of wire that create an internal magnetic field when carrying an electric current - see section 12.1 of the textbook. A solenoid 86.0 cm long has a radius of 3.00 cm and a winding of 1900 turns; it carries a current of 3.60 A. (a) Calculate the magnitude of the magnetic field inside the solenoid in mT. (b) Calculate the magnetic field outside the solenoid in T. (We can treat this as an ideal solenoid, since...

4. (3 pts.) Suppose that you create a simple electromagnet at home by evenly wrapping a thin copper wire 550 times around an 8.0-cm-long iron rod. You then connect the wire to a battery that passes 250 mA through the wire. The iron rod has a radius of 6.0 mm and a magnetic permeability le-150μο. Assuming that this forms an "ideal" solenoid, find the strength of the magnetic field generated inside (and near the ends of) the electromagnet.

39. As an electric current flows through a wire, a. a magnetic field is generated that is inversely related to the current. b. magnetic field lines form around the wire that reverse direction when the current is reversed. c. the lines of magnetic force created closest to the wire are the weakest. d. magnetic lines of force are formed around the wire in the same direction regardless of the direction of the current.

The magnetic field between the poles of an electromagnet is 3.30 T. A coil of wire is placed in this region so that the field is parallel to the axis of the coil. The coil has electrical resistance 24.6 Ω and radius 1.80 cm. When the current supply to the electromagnet is shut off, the total charge that flows through the coil is 9.00 mC. How many turns are there in the coil?
