Magnetic Field inside a Very Long Solenoid

The solenoid has length L, diameter D, and n turns per unit length with each carrying current .It is usual to assume that thecomponent of the current along the z axisis negligible.(This may be assured by winding two layers of closely spaced wiresthat spiral in opposite directions.)From symmetry considerations it is possible to show that farfrom the ends of the solenoid, the magnetic field isaxial.Which figure shows the loop that the must beused as the Ampèrean loop for finding Bz(r) for...

1.) the magnitude of the magnetic field outside of a solenoid is: -almost zero -depends on the type of wire used -depends on the radius 2.) two wires emerge from a clock face at 90° from the face. One wire is at 3 o’clock and has a current of 2.5 A coming out of the clock face. The other is at 9 o’clock and has a current of 5.0A coming out of the clock face. What can we say about...

Carefully measure the magnetic field at the end of the solenoid. How does it compare to the value at the center of the solenoid? Try to prove what the value at the end should be.

In this simulation, you can examine the magnetic field created by the current in a solenoid, which is a cylindrical coil of wire. Instead of using a spiral-shaped coil, the simulation approximates the coil with a stack of seven single loops. The plane of each loop is parallel to the x-z plane, with a radius of either 60 cm or 25 cm, and the displayed field is in the x-y plane. The parallel-plate capacitor is the standard way to create...

The strength of the magnetic field within a solenoid is B = 3.9 x 10-2 T (outside the solenoid B = 0). A smaller, single loop is placed in the solenoid parallel to the plane of each loop in the solenoid. The resistance of the solenoid is 5.4 Ω, the resistance of the loop is 0.29 Ω, the diameter of the solenoid is 0.07 m, and the diameter of the loop is 0.04 m. An emf of 12 V is...
