Muons are one of the twelve fundamental particle types of matter, having relatively long free-particle lifetime. A muon decays into three other light particles (leptons) through action of the “weak” force, transmitted by the so-called “heavy photons” - bosons W+/W-. Muons are present in the secondary cosmic ray showers in the atmosphere and reach the sea level. By detecting the delay time between arrival of the muon and an appearance of the decay electron in our single scintillation detector, we measured the muon’s average lifetime at rest in the material of our detector. This compares well …

Physical Models Of The Toroidal Dipole, Armian Hanelli, Amanuel Eshete, Walerian Majewski
Exigence
We have investigated two models of the third elementary electromagnetic dipole, known as the toroidal dipole. Its magnetic realization is a circumferentially magnetized ring constructed of neodymium. The electric model of the dipole is a toroidal coil connected to a DC voltage. The electric and magnetic toroids produce only an inner magnetic field, inside the torus, and interact only on contact with the electric current density or when immersed in a time-dependent electric field. We studied the characteristics of a permanent-magnet toroid, and observed the influence of electric and magnetic fields on it. A static toroidal dipole moment of this …
