Solenoids are cylindrical coils of wire that create an internal magnetic field when carrying an electric current - see section 12.1 of the textbook. A solenoid 86.0 cm long has a radius of 3.00 cm and a winding of 1900 turns; it carries a current of 3.60 A. (a) Calculate the magnitude of the magnetic field inside the solenoid in...
An ion that is doubly ionized passes through the velocity selector and into the deflection chamber of a mass spectrometer, as shown below. In the velocity selector the electric field has a magnitude of 6958 W/m, and the magnitude of the magnetic field in both the velocity selector and the deflection chamber is 0.0855 T. If in the deflection chamber...
3. The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary potential can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics. Consider an electron trapped by a one-dimensional harmonic potential V(x)=-5 mo?x” (where m is...
Two charges are attached to the vertical axis as shown in the figure below. #4C 04 (a) Calculate the electric potential at Point A due to the two charges. (b) Calculate the electric potential at Point B due to the two charges. V (c) Calculate the electric potential difference of Point A relative to Point B. V

4. Before television screens were all flat, they used to work by boiling off electrons ("cathode rays") from plates a hot filament and accelerating them towards a phosphor-coated screen. The acceleration was performed with a pair of charged parallel plates, as in a capacitor, with small holes to allow the beam to pass through. The beam was steered horizontally and...
Suppose a power line produces a 5.1×10−4-T peak magnetic field 60 times each second at the location of a neuron brain cell of radius 6.0 ×10−6 m. Determine the maximum magnitude of the induced emf around the perimeter of this cell during one-half cycle of magnetic field change.
In Oersted's experiment, suppose that the compass was 0.15 m from the current-carrying wire. If a magnetic field of one third the Earth's magnetic field of 5.0×10−5T was required to give a noticeable deflection of the compass needle, what current must the wire have carried? Express your answer using two significant figures.
