A simple electric motor is a great tool in teaching middle school aged children how electricity and magnetism can work together. By attaching magnet wire to a battery and placing it in a magnetic field, the current flowing through the circuit creates an electromagnetic field.

In the similar way, a changing magnetic field produces an electric current in a wire or conductor. The relationship between electricity and magnetism is called electromagnetism. Electricity and magnetism is an interesting aspect of electricity sciences.

In a generator, the physical motion of a magnetic field produces electricity for power. In a transformer, electric power is converted from one voltage level to another by the magnetic field of one circuit inducing an electric current in another circuit.

“EMF” is an abbreviation for “electric and magnetic fields” and “electromagnetic fields.” Power lines, appliances, and home wiring all produce electric and magnetic fields. “EMF” is also often used by people as shorthand for just “magnetic fields,” which some people are concerned about, so that is what “EMF” refers to here.

Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets , producing magnetic fields themselves.

Electric and Magnetic Fields (EMF) The strength of the electric field is measured in units of volts per meter (V/m). Electric fields often are present even if the equipment is turned off, as long as it remains connected to the power source. Electric fields decrease rapidly the further you get from the source.

electric and magnetic fields occur through hu-man activity wherever electricity is generated, transmitted and used. The Difference Between Electric and Magnetic Fields Electric fields Electric fields are produced by voltage. Voltage is the pressure behind the flow of electricity. It can be compared to the pressure of water in a hose.

The amount of electric current refers to the number of electrons (to be precise, their charges) passing through an area per unit of time, and is measured in amperes (usually called amps for short, abbreviated with a capital A). One ampere equals roughly 6.24 × 1018 or 6.24 quintillion electrons passing in 1 second.
