Question
1- the overall B field produced by a current carrying solenoid is much like the field produced by a bar magnet. ( a) True (b) false
2- Real solenoids typically have several layers of coils wound on top of one another. What is the purpose of winding the solenoid in this manner ?
3- For an ideal solenoid, which best describes the B field outside and inside the solenoid ?
(a) B is zero inside the solenoid and large and parallel to the axis outside the solenoid.
(b) B is zero outside the solenoid and large and perpendicular to the axis inside the solenoid.
( c) B is the large and parallel to the axis inside the solenoid and large and parallel to the axis in the opposite direction outside the solenoid,
(d) B is zero outside the solenoid and large and parallel to the axis inside the solenoid.
4- a solenoid has N=1,000 turns of wire and its length is L=0.150 m . what is the value of the B field produced by the solenoid at its center if the current in the current in the wire is 3.00 A ? show your work.
5- For the solenoid of question 4,what would be the value of the B field at the end of the solenoid along its axis ? show your work.
Explanation / Answer
1. True. The magnetic field pattern around a solenoid is similar to the magnetic field pattern around the bar magnet which had a definite north and south pole
2. A completed coil assembly with one or more set of coils and taps is often called the windings. The purpose of several layers of winding is to provide additional insulation and secure them in place..
3. The answer is (c)
4. B = ?ni
where B = magnetic field in tesla, n = no of turns per unit length(length/m), I = current in ampere, ? = 4? * 10^-7 T/amp m....here n = 1000/0.150, i = 3A
so B can be calculated
5. Magnetic Field at the end of the solenoid = ?ni/2
