In summary, Purcell's magnetism problem, also known as the "magnetic moment problem," refers to the discrepancy between experimental measurements and theoretical predictions of the magnetic moment of subatomic particles. It was first discovered in the mid-20th century by Edward Mills Purcell, a Nobel Prize-winning physicist, while studying the magnetic properties of the electron. The significance of this problem lies in its challenge to our understanding of fundamental particles and their interactions, and resolving it could lead to a more accurate understanding of subatomic behavior. Proposed solutions include the existence of new, undiscovered particles or interactions, modifications to current theories of electromagnetism, and the possibility of experimental errors. However, this problem has not yet been definitively solved, but ongoing

Homework Statement



The figure shows the path of a positive ion moving in the xy plane. There is a uniform magnetic field of 6000 gauss in the z direction. Each period of the ion's cycloidal motion is completed in 1 microsecond. What is the magnitude and the direction of the electric field that must be present? Hint: Think about a frame in which the electric field is zero.
