Electricity and Magnetism

Magnetism is generated by moving

• protons.
• electrons.
• neutrons.
• elements.

What do the lines around this magnet represent?

• North Pole
• South Pole
• Magnetic Declination
• Magnetic Field

If you place the North pole of a magnet next to the South pole of another magnet, they will:

• Attract
• Repel
• Do nothing
• Shatter

What happens when two north poles of a magnet are placed together?

• they repel
• they attract
• they cancel each other out
• the strength of the magnet is doubled

In un-magnetized materials the domains are __________ aligned.

• super
• slightly
• randomly
• always

Electric motors are devices that convert _____ energy into  _____ energy.

• chemical; potential
• mechanical; kinetic

What kind of magnet can be turned on and off?

• refridgerator magnet
• electromagnet
• magnetite
• iron

• Magnetic field 
• Magnetic force
• Domain
• Perimeter

Two south poles will...
