Magnetism Review
... Explanation: A force is exerted on charged particles only when they move at an angle to magnetic field lines. The force is greatest when motion is at right angles to the magnetic field. ...

Why won`t my compass work the other side of the equator
... The Earth’s magnetic field is three dimensional in the same way as the field of any magnet. It is because of the Earth’s 3D magnetic field that the magnetic needle of a compass has to be weighted so that it floats horizontally in one hemisphere; but this means that the weight is on the wrong end ...

Heat Capacity Studies of NdNi4Si Compound
... H = 9 T). The ferromagnetic NdNi4 Si was characterized by the electronic heat capacity coefficient γ = 85 mJ/(mol K2 ) and the Debye temperature ΘD = 325 K. Zero field heat capacity reveals a peak close to the magnetic ordering temperature. The maximum is shifting to higher temperatures with increas ...

Maxwell`s equations
... When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in ...
