Friendly reminder you can check your notes from Knotion ch6, Sessions 14 and 17 while answering this quiz. Are you ready?

• Yes! I have my notes with me.

• No

It is the property of attracting metals such as iron, cobalt, nickel...

• Electricity

• Magnetism

• Electromagnetism

• Electrostatic

It's the region that sorrounds any magnetic material

• Magnetic field

• Attraction

• Repulsion

• North and South

What does the labels "NORTH" and "SOUTH" in a magnet refer to?

• The two poles in a magnet

• The direction to which the magnet is oriented

Pay attention to the poles facing each other in these two magnets. What type of force do they experience?

• Attraction

• Repulsion

Which is the only mineral that has natural magnetic properties?

• Magnesium

What would happen if you cut a magnet into two parts?

• You would have two new magnets, each one with new north and south poles.

• You would have a "North pole" magnet, and a "South pole" magnet.

• The magnet would stop working.

• Magnets cannot be cut into pieces.

How is an electric current induced?

• By moving a magnet repeatedly inside a conductor in the form of a coil.

• By leaving a magnet inside of a conductor in the form of a coil.

• By placing a magnet near a conductor in the form of a coil.

The amount of voltage that can be produced depends on... (select all that apply)

• The speed with which the magnet moves inside the coil

• The number of coils in the wire.

• The direction of the poles in the magnet
