    Solenoid with current carrying wire inside

    I forgot my directions. Does the wires having a different value for mu than air affect anything? I solved it first using H and then I got to getting the magnetic field and I was confused how it would affect it.

    What is the width of a square well if its ground-state energy is 2.50 eV?

    Homework Statement An electron is bound in a square well of depthU0=6E1−IDW. What is the width of the well if its ground-state energy is 2.50 eV ? Homework Equations En = h2n2/8mL2 The Attempt at a Solution I used n = 1 so I get: 25eV*1.6*10-19 = h2/8*9.11*10-31*L2 I got L = .388 nm. It...

    What is the formula for a magnetic field due to a finite wire with current?

    Homework Statement A rectangular loop with dimensions 4.20 cm by 9.50 cm carries current I. The current in the loop produces a magnetic field at the center of the loop that has magnitude 3.60×10−5T and direction away from you as you view the plane of the loop. Homework Equations b = mu_0 I L/...

    Cyclotron magnetic field questions

    Homework Statement Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. These cyclotrons typically accelerate H− (the hydrideion, which has one proton and two electrons) to an energy of 5MeV to 20MeV. This ion has a mass very close to that of a proton...
