Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their axial direction. For example, they are traditionally used in the experiment for the measurement of the charge to mass ration of the electron. Helmholts coils are two coils separated by a distance equal to their radius and also carry equal currents in the same direction, as shown in the figure on the right. Supposed the radius of the coil is 15.00 cm, each coil...
6. A very long solenoid has a density of coils n turns per unit length. We apply a current I through the solenoid. Use Biot-Savart law to derive the magnetic field in the center of the the solenoid. Verify that it agrees with the result from the Ampere's law. You can approximate the solenoid as infinitely long 6. A very long solenoid has a density of coils n turns per unit length.

1 Mass Measurement What we do to measure the mass of subatomic particles is to shoot them into a magnetic field and measure the resulting circular path. We set up the magnetic field region with a current in two Helmholz coils (see your homework problem 30.61). Basically, this means that the field has equal contributions from each coil; each coil produces a magnetic field measured some distance z away from the center of N loops of wire: Nuo R B=...
2. Briefly discuss the Biot Savart Law and give its mathematical expression. (5 Marks) a. b. An infinitely long straight conductor is present in a magnetic field B. The conductor carrying a current of I = 10 A, is placed in a sheath (M- 202 ). At what distance from the conductor will the magnetic field be 1T/m? Find the magnetic moment of a square loop of 500 turns in a field of uniform flux density 2.5mT. The loop carries...
Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...
