A rectangular loop with width L and a slidewire with mass m are as shown in figure 1. A uniform magnetic field B is directed perpendicular to the plane of the loop into the plane of the figure. The slidewire is given an initial speed of v0 and then released. There is no friction between the slidewire and the loop, and the resistance of the loop is negligible in comparison to the resistance R of the slidewire. (A) obtain and expression for F, the magnitude of the force exerted on the wire while it is moving at speed v. Express your answer in terms of some or all variables B, v, R, L, and m. (B) find the distance x that the wire moves before coming to rest. Express your answer in terms of some or all of the variable B, v0, R, L, and m.

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.
