A sample of the paramagnetic salt to which the magnetization curve of the figure applies is held at room temperature (340 K). At what applied magnetic field will the degree of magnetic saturation of the sample be (a) 25% and (b) 75%? (c) Are these fields attainable in the laboratory?**Graph Description:**The graph displayed shows the ratio of magnetization \(\frac{M}{M_{\text{max}}}\) versus the ratio of the applied magnetic field magnitude \(B_{\text{ext}}\) to the temperature \(T\). The y-axis is labeled \(\frac{M}{M_{\text{max}}}\) ranging from 0 to 1. The x-axis is labeled \(\frac{B_{\text{ext}}}{T}\) (T/K) ranging from 0 to 4.0.Colored markers representing different temperatures (1.30 K, 2.00 K, 3.00 K, 4.21 K) trace curves that start from the origin and approach \(\frac{M}{M_{\text{max}}} = 1\). Curie's law appears as a straight line on the graph fitting the initial data points, while the curves adhere to quantum theory as they progress.**Text Explanation:**A magnetization curve for potassium chromium sulfate, a paramagnetic salt. The ratio of magnetization \(M\) of the salt to the maximum possible magnetization \(M_{\text{max}}\) is plotted versus the ratio of the applied magnetic field magnitude \(B_{\text{ext}}\) to the temperature \(T\). Curie’s law fits the data at the left; quantum theory fits all the data. After W. E. Henry.---(a) Number: [______] Units.(b) Number: [______] Units.

The Hall effect can be used to determine the density of mobile electrons in a conductor. A thin strip of the material being investigated is immersed in a magnetic field and oriented so that its surface is perpendicular to the field. In a particular measurement, the magnetic field strength was 0.735 T, the strip was 0.101 mm thick, the current along the strip was 2.95 A, and the Hall voltage between the strip's edges was 2.95 mV. Find the density n of mobile electrons in the material. The elementary charge is 1.602 x 10-19 C. 1.56 x104 n 3= -3 Incorrect

Let's estimate what kinds of conditions a "military grade" railgun would require. First of all, let's say the muzzle velocity has to be 1000 m/s (actually slow for a railgun). The magnetic field has to be big and so let's choose 10 T. For the gun length, let's choose L = 5 m. Suppose mass of the rod is 0.1 m and its length is 20 cm. The rod maintains contact as it slips. Ignore rolling. L a) Calculate the force that must be acting on the rod. b) To achieve this force, what current must be delivered to the rod?
