All of the following elements produce magnetic fields except for

a. copper

b. iron

c. Nickel

d. Cobalt

Answer: a. copper

A magnetic field is a condition of space around a metal or object that causes other objects to be attracted to it. It can be created by passing electricity through an object (usually a magnetic object), as it is the result of electrons in motion.

When electricity is passed through them, iron, nickel, and cobalt are able to produce magnetic fields around themselves, while copper is unable to. When exposed to a magnet, copper is not attracted to the magnet, whereas the electrons on the surface of the copper begin to rotate.

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]
