... The reason alternating current is used for the transmission of power to our homes is due to the ease in stepping up or down voltage by using transformers. Since resistance depends upon length, transmitting energy long distances would result in a significant amount of energy lost in heating of the tr ...

An alternative way of producing the magnetic flux density, would be to use a superconducting magnet instead of a permanent magnet while continuing to use the suspended coil at liquid helium temperatures. A possible design of this alternative system is shown in Figure 2. Such a configuration would ha ...

Understanding electric and magnetic fields
... Electric fields are created by voltage (the flow of power). Magnetic fields (the force of power being discharged while electricity is moved) are created by alternating current. To illustrate, an electric field will be present around a lamp that is plugged in but not turned on. A magnetic field will ...
