Question

define magnetic effect of electric current.

Answer 1

Magnetic effect of electric current is one of the major effects which functions as the basic principle in appliances used in various fields of activities. The magnetic field around a current carrying conductor can be depicted by using magnetic field lines which are represented in the form of concentric circles around it. The direction of magnetic field through a current carrying conductor is determined by the direction of flow of electric current.

Answer 2

1. The term ‘magnetic effect of electric current’ means that an electric current flowing in a wire produces a magnetic field around it . A iron, steel, nickel and cobalt. A bar magnet is a Magnet is an object which attracts pieces of long, rectangular bar of uniform cross-section which attracts pieces of iron, steel, nickel and cobalt.

2. The region surrounding a magnet , in which the force of magnet can be detected is said to have a magnetic field.  Magnetic field is a quantity that has both magnitude and direction ; as such it is a vector quantity.  The term is used for two distinct but closely related fields denoted by the symbols B and H, which are measured in units of tesla and amp per meter respectively in the SI.B is most commonly defined in terms of the Lorentz force it exerts on moving electric charges.
