Lecture 19: Magnetic properties and the Nephelauxetic effect
... The value of λ is negligible for very light atoms, but increases with increasing atomic weight, so that for heavier d-block elements, and for f-block elements, the orbital contribution is considerable. For 2nd and 3rd row dblock elements, λ is an order of magnitude larger than for the first-row anal ...

Magnetic Induction
... Iona Prep Physics Lab Magnetic Induction When an electric current flows in a circuit it produces a magnetic field. Another way of saying that is “a moving charge generates a magnetic field”. Michael Faraday reversed the process. By passing a magnet through a coil, he produced a voltage. Another way ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
