The Hall voltage across a conductor in amagnetic field is. When used with the same current in a different magnetic field, the voltage across the conductor is. What is the strength of the second field?
What is the initial direction of deflection for the charged particles entering the magnetic fields in the figure
A current circulates around a diameter superconducting ring.
a. What is the ring’s magnetic dipole moment?
b. What is the on-axis magnetic field strength from the ring?
Points 1 and 2 in FIGURE EX 29.2 are the same distance from the wires as the point where . What are the strength and direction of at points 1 and 2 ?
To five significant figures, what are the cyclotron frequencies in a magnetic field of the ions , , and ? The atomic masses are shown in the table; the mass of the missing electron is less than u and is not relevant at this level of precision. Although and both have a nominal molecular mass of , they are easily distinguished by virtue of their slightly different cyclotron frequencies. Use the following constants:.
