Electromagnetic conduction involves creating an electric current using magnets and a coil of wire. Watch the demonstration. What is created when the North and
South magnetic poles are placed close to each other?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
