A particle carrying a charge of 2.0 x 10‐5 C is moving along the +z axis at a speed of 4.2 x 103 m/s. SpletEvery atom of a magnetic material behaves as a magnetic dipole, because electrons in the atom revolve around the nucleus. The magnetic moment M associated with an atomic dipole as. where n = 1, 2, 3 ….. denotes the no. of orbits and . Least value of dipole moment of atom = 9.27 × 10–24 Am2.
SpletEvery north and south pole of a magnet needs to also have its opposite side, but field lines can even travel from one magnet to a different one. Magnetic field lines don’t “really” exist. They are a conceptual tool to help us understand magnetic behavior. The field lines track potential energy.

SpletA magnet is a rock or a piece of metal that can pull certain types of metal toward itself. The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. This …
SpletMost materials can be classified as diamagnetic, paramagnetic, or ferromagnetic. Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and do not retain the magnetic properties when the external field is removed.
