... magnetic fields according to the same law (2) as holds for conduction currents. However, Slepian also reminds us that if the displacement current is placed in an external magnetic field, say B0 , then it does NOT experience a force (density) that is the analog of the force (density) J/c × B0 on a co ...

Electrostatics The Nature of Electric Charge
... Charges are arbitrarily called positive and negative. In most cases, only the negative charge is mobile. Properties of charge Like charges repel, unlike charges attract. Charge is conserved: it cannot be created or destroyed. Charges aren’t “used up”, but their energy can be “harnessed”. Electrons a ...
