You would like to store 9.7 J of energy in the magnetic field of a solenoid. The solenoid has 600 circular turns of diameter 8.2 cm distributed uniformly along its 28 cm length. 1. How much current is needed? 2. What is the magnitude of the magnetic field inside the solenoid? 3. What is the energy density (energy/volume) inside the solenoid?

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...

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 potential energy of a magnetic moment in an external magnetic field is U = -...

The potential energy of a magnetic moment in an external magnetic field is U = - ??B. U is smallest when B is parallel to ? and largest when it is antiparallel. Since the magnetic moment of the electron is directed opposite to its spin (because it has a negative charge), the electron’s energy is highest when the spin is parallel to B. The two possible energy states for the electron are the spin up state (ms = 1212) and...
