... 4. interior field lines are parallel and closely-spaced indicating a uniform field. External fields are weak because current elements on right side of turn cancel fields from the left sides of turn. 5. with more and closely-spaced turns, a solenoid becomes more ideal and approaches that of a bar mag ...

A changing magnetic field (flux) can create an emf (ΔV)
... There are no free magnetic charges. Magnetic field lines diverge from N poles and converge into S poles, but they do not begin or end at either pole. Then Qmagnetic = 0, so that there cannot be enclosed charge. Gauss’s Law for magnetism is then: r r ...

Magnetism
... In ferromagnetic compounds μeff is generally much greater than μspin-only due to the cooperative effect of the spins coupling in parallel which reinforces the bulk magnetic moment. The most common ferromagnetic materials are metals such as iron and cobalt and their alloys. CrO2 is a rare example of ...

Faraday`s Law
... 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 ...
