- at a microscopic level, something similar to a circular electrical current is occurring. Using what you know about atoms, suggest a reason there may be something like "circular current" at a microscopic level in a bar magnet.Find the acceleration in Pm/s2 (1P = 1015, for theelectron in problem #48.a. using a chargedensity of o = 3.54 uC/m2.A 4.3-MeV (kinetic energy) proton enters a 0.21-T field, in a plane perpendicular to the field. What is the radius of its path?
- The top of the atmosphere is at about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm-1 Why then do we not get an electric shock as we step out of our house into the open? (Assume the house to be a steel cage so there is no field inside!)Please type instead of hand writtingThe magnetic dipole moment of the gadolinium atom is about 6.3 ✕ 10−23 A · m2. (a) Calculate the maximum magnetic dipole moment (in A · m2) of a domain consisting of 1019 gadolinium atoms. (b) What current (in A) would have to flow through a single circular loop of wire of diameter 1.2 cm to produce the magnetic dipole moment you calculated?
- Estimate the diamagnetic and paramagnetic electron spin susceptibility of a hydrogen atom gas at room temperature. Compare your magnitudes.An alpha particle moving to the east enters a region of uniform magnetic field pointing straight up. Describe the subsequent motion of the alpha particle.A docs.google.com/forms/d/e. In the Hall Effect, the magnetic field is in z direction and the velocity is in x direction. ?What is the direction of the electric field z O Y O What does p/T represent? Where T is life time holes per second lost time holes Measurement of Hall coefficient in a semiconductor provides information on :the Sign and concentration of charge carriers Sign of charge carriers alone Mass and concentration of charge carriers
- Hall potentials are much larger for poor conductors than for good conductors. Why?Two long, parallel wiresseparated by a distance 2d carryequal currents in the same direction.An end view of the two wiresis shown in Figure P19.54, wherethe currents are out of the page.(a) What is the direction of themagnetic field at P on the x - axisset up by the two wires? (b) Find anexpression for the magnitude of thefield at P. (c) From your result to part (b), determine the fieldat a point midway between the two wires. Does your resultmeet with your expectation?
