Difference between Electric and Magnetic Fields


Difference between Electric and Magnetic Fields

Compare, distinguish and explain what is the difference between Electric and Magnetic Fields. Comparison and Differences.

Difference between Electric and Magnetic Fields

1. Electric fields are produced by voltage. Magnetic fields are produced by current.

2. Electric fields are created by differences in voltage: the higher the voltage, the stronger will be the resultant field. Magnetic fields are created when electric current flows: the greater the current, the stronger the magnetic field.

3. An electric field will exist even when there is no current is flowing whereas if a current does not flow, then the strength of the magnetic field will vary with the power consumption.

4. Electric fields are measured in volts per meter (V/m). Magnetic fields are measured in gauss (G) or tesla (T), 1 Tesla = 10000 Gauss.

5. Electric field can be easily shielded (weakened) by conducting objects, such as metal. trees and buildings. Magnetic field can not be easily shielded (weakened).

6. Strength of both the electric and magnetic fields drops off quickly as distance increases (unlike radio waves).
