Fig. 1 25. A strip-like conductor with dimensions a b c = 6.0.5.6 mm³ is serving as a Hall-probe. A current of 40 mA is flowing, and the sample is placed in a magnetic field B = 0.8T, as a result a Hall-Votlage of UH = 20 mV is measured. a) What is the charge carrier concentration in the sample? b) What side of the strip-like probe accumulates negative charge if the charge transport is done via electrons? c) What Hall-voltage arises from bipolar conduction, hence when the same amount of electrons and holes contribute to the conduction? Electrons and hole can be assumed to have equal mobility. Fig. 2
A Hall probe serves to measure magnetic field strength. One such probe consists of a poor conductor 0.135 mm thick, whose charge‑carrier density is 1.01×1025 m−3. When a 1.97 A current flows through the probe, the Hall voltage is measured to be 4.29 mV. The elementary charge ?=1.602×10−19 C. What is the magnetic field strength ??
Two concentric metal spherical shells, of radius a and b, respectively, are separated by weakly conducting material of conductivity ơ (see part (a) of figure). (a) (b) a. If they are m aintained at a potenti al difference V, what current flows from one to the other? b. What is the resistan ce between the shells? c. Notice that if b > a the outer radius bis irrelevant. How do you account for that? Exploit this observation to determine the current flowing between two metal spheres, each of radius a, immer sed deep in the sea and held quite far apart (see part (b) of figure), if the potential difference between them is V. (This arr angement can be used to measure the conductivity of sea water.)
Two straight, parallel, superconducting wires 7.06 mm apart carry equal currents of 12958 A in opposite direction. Calculate the force experienced in a 0.5m length.

Q. 5: (a)The Hall effect can be used to calculate the charge-carrier number density in a conductor. If a conductor carrying a current of 2.0 A is 0.5 mm thick, and the Hall effect voltage is 4.5µV when it is in a uniform magnetic field of 1.2 T, what is the density of charge carriers in the conductor?
calculate the relative strength of the interaction between two typical magnetic dipoles, compared with the interaction between two typical electric dipoles. To be explicit, calculate the torque exerted on one dipole by the other when they are oriented perpendicularly to each other at a distance of one ansgtrom unit; take each magnetic dipole =1 Bohr magneton, each electric dipole =e x 0.1 angstrom. This calculation shows that the basic magnetic interaction is several orders of magnitude smaller than the electrical interaction in matter.
