High Current Through A Wire Causes Magnetic Field. The field is stronger with more turns of the wire. Strong magnetic fields inside a home or building can be caused by many factors:
PPT Notes I. refers to the properties and from www.slideserve.com
The field reverses when the current is reversed. 1) external sources such as high voltage transmission lines or a large transformer. The magnetic field lines generated around the wire due to the presence of the current are depicted in blue.
