Webquestion_answer 24) Due to the earth's magnetic field, charged cosmic ray particles. A) require greater kinetic energy to reach the equator than the poles. B) require less kinetic energy to reach the equator than the poles. C) can never reach the equator. D) WebThe magnetic moment is a directional vector. There are two kinds of spin modes of electrons in atoms. In most matter, there are as many electrons with upward and downward spins, and the magnetic moments they produce will cancel each other out, and the entire atom is not magnetic to the outside. Only the atoms of a few matters have different ...
Web2 feb. 2024 · Paramagnetism (opens in new tab) occurs when a material becomes magnetic temporarily when placed in a magnetic field and reverts to its nonmagnetic state as soon as the external field is removed. Web12 sep. 2024 · We can use the Biot-Savart law to find the magnetic field due to a current. We first consider arbitrary segments on opposite sides of the loop to qualitatively show by the vector results that the net magnetic field direction is along the central axis from the loop.
Web11 apr. 2024 · Concept : Atoms have dipole moments due to the motion of their electrons around the nucleus and the spin of the electrons. In general, these dipole moments are not aligned and cancel each other out and make a material non-magnetic. Ferromagnetic materials have the ability to arrange these moments under special circumstances in a …
