i need help please mTA Hall-effect probe operates with a 120 -mA current. When the probe is placed in a uniform magnetic field of magnitude 0.0880 T, it produces a Hall voltage of 0.800 μV.(a) When it is used to measure an unknown magnetic field, the Hall voltage is 0.320 μV. What is the magnitude of the unknown field?M-3(b) The thickness of the probe in the direction of B is 1.80 mm. Find the density of the charge carriers, each of which has charge of magnitude e).

Cathode ray tubes in old television sets worked by accelerating electrons and then deflecting them with magnetic fields onto a phosphor screen. The magnetic fields were created by coils of wire on either side of the tube carrying large currents. In one such TV set, the phosphor screen is 50.6 cm wide, and is 10.1 cm away from the center of the magnetic deflection coils (that is, the center of the region of magnetic field). The electron beam is first accelerated through a 15,000 V potential difference before it enters the magnetic field region, which is 1.00 cm wide. The field is approximately uniform and perpendicular to the velocity of the electrons. If the field were turned off, the electrons would hit the center of the screen. What magnitude of magnetic field (in mT) is needed to deflect the electrons so that they hit the far edge of the screen? Ignore any relativistic corrections. mT

2. Using the IV plots shown in Fig. 3 (and found in the reintroduction to PSpice) design a BJT biasing circuit that results in the following parameters: VCE = 2 Vand ig = 40 μA. We also require the power supply to be fixed at 5 Volts (this is where the load line intercepts the iB =ic = 0 line). You may use the circuit shown in Example 1. Note that all resistor values in Example 1 must be recalculated. Your solution for the base to ground and base to collector resistors may not be unique.
