What is the direction of the magnetic field at point P due to the current I,?O UpDownRightLeftInto (the page)O Out of (the page) Sum of fieldsThe sequence of questions on the right will guide you to calculate the net magneticfield at a point due to multiple sources.In the case shown in the figure below, the sources of the magnetic field are twocurrent-carrying wires.Wire-1 carries a 12A current pointing Up, and Wire-2 carries a 10A currentpointing Left. (indicated by (b) on the figure.)12 A15 cm10 A(a) >(b)8.0ст8.0cm15 cmThe net magnetic field at any point can be calculated as the vector sum of the fieldcontributions from each wire.In other words, to find the net field, we need to find the field from each wire, andtheir relative orientations. If the fields point in the same direction, theirmagnitudes add up. If they point in opposite directions, then the net field'smagnitude is the difference between the magnitudes, and the direction is that ofthe stronger field.

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.
