- The Hall affect is used to measure the carrier density of a thin sheet of electrons. When a current of 80.0 µA flows through the length of the electron sheet, which is 1.2-mm long, 0.27- mm wide and 12-nm thick, a magnetic field perpendicular to the sheet produces a potential difference of 0.53 mV across the width of the sheet. If the carrier density in the electron sheet is 6.74 x 1025 m-3, what is the magnitude of the magnetic field?How the Biot-Savart Law Differs from Ampère's Law A current Io flows up the z-axis from z = z, to z = 22 as shown below. %3D Z2 (a) Use the Biot-Savart law to show that the magnetic field in the z = 0 plane is Ho lo {cos 02 – cos 01}6. 4π ρ B(p, 6, 0) = |4+ 71.

The beta particle is moving up along the screen with a speed equal to 86.3% of the speed of light c, and the uniform field points to the right. a) In what direction will the beta particle be deflected? Explain briefly how you got your b) answer. s What will be the magnitude of the magnetic force (in N) acting on the beta particle? Show your work. Without doing another calculation, what magnitude of magnetic force would an alpha particle, moving with the same speed as the beta particle, experience in this magnetic field? Explain your answer briefly.An electron moves in an uniform magnetic field (with the orbital plane perpendicular to the field). If the cylotron radius of the electron is 60 cm and it's kinetic energy is 9.6 keV, find the electron's speed, the magnitude of the magnetic field, the cyclotron frequency, and the period of the motion.
