The strength of an electromagnet can be increased by increasing the cross-sectional area, increasing the number of turns, increasing current supply, increasing the length of the coiled wire.

Conduction is the movement of heat through a substance by the collision of molecules. It occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature.

The kilowatt hour (kW⋅h) is a composite unit of energy equivalent to one kilowatt (1 kW) of power sustained for one hour.

One watt is equal to 1 J/s. One kilowatt hour is 3.6 megajoules.

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. The force that generates wind is called as Pressure gradient force.

Biotin is a water-soluble B vitamin, also called vitamin B7 and formerly known as vitamin H or coenzyme R.
