Ecological pyramids are graphical representations of the trophic structure of an ecosystem. Regarding these pyramids, check the incorrect alternative.
A) A pyramid is called a number pyramid when it tells you how many individuals there are at each tropic level.
B) The biomass pyramid can be inverted.
C) An energy pyramid can never be reversed.
D) The base of a pyramid is not always represented by the producer. E) A biomass pyramid represents the amount of organic matter found at each tropic level
C. is the wrong option. This is because  it represented the energy fixed in each tropic level . it is never inverted because it flow upwards in the ecosystem.  This energy reduces upwards the pyramid, it is largest at the base of the  producers, and decreases in amount as it flow upwards from one organism at each trophic level to another. This is because each organism uses the energy for biological work

Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil". 
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.
