It is fairly easy to build an electromagnet. All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism.
It is False that, If f '(c) = 0, then f has a local maximum or minimum at c.
Local maximum and minimum points are very distinctive on the graph of a function and are thus, helpful in grasping the shape of the graph. Either a local minimum or a local maximum can be considered a local extremum.
A counterexample can be used for:
f(x) = x³
f'(x) = 2 × x²
and,
f'(0) = 2×0² = 0
However, the assertion is false because x = 0 is actually an inflection point rather than a maximum or minimum in f(x) = x³.

Microwave and Infrared Radiation. Both are forms of electromagnetic radiation. Both are transmitted as waves. Waves are converted to heat.
