Friday's Fact

It’s called “bug juice” and it is used by doctors to remove warts. What is the name of the substance and where does it come from?

Last week’s fact: An earlier post described maglev or magnetic levitation as applied to high speed trains. The concept of using electro-magnets to propel objects is being applied in another unique area. Can you name it?

Ahamed correctly identified using electro magnets for defense issues (guns/canons) or what is known as a rail gun which propels an object at extremely high speeds.

Another application is known as EMALS or electro-magnetic aircraft launching system for aircraft carriers. The beauty of this type of propulsion system is the precise acceleration control that is inherent in the technology.
