An electron travels above a sheet carrying a uniform current per unit width. When an electric field of magnitude 200 v/m is applied, the electron moves in a straight line with a constant velocity of 3.0 x 10° m/s parallel to the sheet, at an angle of 45° to the current in the sheet. What is the magnitude of the current per unit width in the sheet? You can use the result that the magnitude of the magnetic field, B of a sheet carrying a uniform current per unit width, K is B =HoK, where Ho = 47 x 10-Tm/A

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.
