ElectricityElectric fields are caused by electric charges, time-varying magnetic fields, or both.Magnetic fields are created by permanent magnets or by currents, i.e., by moving electric charges.A moving electric charge is surrounded by an electric field and a magnetic field. In its rest ...
Today, I can describe how a magnetic field makes an electric current. April 28, 2015 Faraday’s Experiment Hans Christian Oersted discovered that an electric current could make a magnetic field. Faraday set up an experiment to test whether the magnetic field of the electromagnetic would make an ...

No studies unequivocably demonstrate deleterious effects of ELF electric or magnetic field exposure on mammalian reproduction and development, but several suggest such effects. Exposure to ELF electric and magnetic fields does produce biological effects. However, except for fields strong enough to induce...

The motion of these holes accounts for most of the conduction of electricity in zinc. If a wire with a current i is placed in an external magnetic field B, how will the force on the wire depend on the orientation of the wire? Since a current represents a movement of charges in the ...

This micro-encapsulated film enables students to view a static magnetic field, such as found around permanent magnets or DC electromagnets. Simply place the film directly on the surface of the magnetic material in question and instantly reveal a magnetic field of any shape or pattern. You can ea...
Why do magnetic field lines go from north to south? Why are magnetic field lines closed curves? What is the purpose of the Earth's magnetic field? Why are electricity and magnetism related? Why doesn't the moon have a magnetic field?
